The bark of low back pain is usually much worse than its bite. The pain almost always makes it seem worse than it is.
MRI and x-ray for low back pain are surprisingly unreliable,1 because things like bulging discs usually aren’t a deal,2 most back pain goes away on its own,3 and trigger points (“muscle knots”) are common and can be alarmingly intense but aren’t dangerous.4 Most patients are much better off when they feel confident about these things. The power of justified, rational confidence is a huge factor in back pain.5 Sadly, many healthcare professionals continue to perpetuate the idea of fragile backs,6 which undermines that valuable confidence.
Or you could be dying! What are the odds that back pain is something scary?
There are cases of low back pain that have alarming causes, but it’s rare. Once in a while back pain is a warning sign of cancer, autoimmune disease, infection, or a handful of other scary culprits.7 Over the age of 55, about one in twenty cases turns out to be a fracture, and one in a hundred is more ominous.8 The further you are from 55, the better your odds.
But how can you tell? It can be tricky. This is a concise, readable guide to symptoms that need better-safe-than-sorry investigation with your doctor. (It’s basically just a plain English version of clinical guidelines for doctors.9) In other words, this article explains the difference between “dangerous” and “just painful” as clearly as possible. Tables, checklists, and examples ahead.
Ordinary back pain can be fierce & awful … but not dangerous. It’s bark is almost always much louder than its bite.
Chronic low back pain is serious … but rarely ominous
Back pain can suck the joy out of your days for week, months, even years. It can definitely be “serious” even when it’s not dangerous. I have worked with many truly miserable chronic low back pain patients, and of course the huge economic costs of back pain are cited practically anywhere the subject comes up. But your typical case of chronic low back pain, as nasty as it can be, has never killed anyone.
“Ominous” is medical jargon for “truly scary.” Cue Jaws theme music. Low back pain is ominous when it is caused by something that can cripple or kill you. Such causes are rare, fortunately. But awful things do happen, even the best doctors can miss them (and “alternative” health care professionals are even more likely to).
All of the worst possible causes of back pain and their major features
None of these are common. All of them usually cause serious symptoms that are easy to take seriously. Some of them can “fly under the radar” in early stages, but usually not for long. The names of the conditions link to carefully chosen articles from good sources.
|what is it?||major features|
|cancer||a tumor in or near the spine||Many kinds of cancer can cause many kinds of back pain, but some strong themes are: the pain grows steadily and is mostly unaffected by position and activity, worse with weight bearing and at night, and comes with other signs of being unwell.|
|cauda equina syndrome||pinching of the lowest part of the spinal cord||Hard to mistake for anything else: hard to pee, fecal incontinence, numb groin, weak legs. Caused by ruptured discs, trauma, cancer, infection.|
|spinal infection||infection in or near spinal structures||Hard to detect, often for a long time. Usually there’s a well-defined tender spot and then, eventually, deep constant pain, a rigid spine, sometimes fever and illness but not always.|
|abdominal aneurysm||ballooning of a large artery next to the spine||Pain may throb in sync with pulse. Mostly occcurs in people at risk of heart disease: older, heavier, hypertensive smokers and diabetes patients.|
|ankylosing spondylitis||inflammatory arthritis of spine and pelvis, mostly||Long term back pain starting well before middle age and progressing slowly and erratically, improves with activity but not rest, prolongued morning stiffness, possible involvement of other areas. More common in men.|
The worst back pain is rarely the scariest
People understandably assume that the worst back pain is the scariest. In fact, pain intensity is a poor indicator of back pain ominousness,10 and some of the worst causes are actually the least painful (especially in the early stages). For instance, someone could experience the symptoms of cauda equinae syndrome, and be in real danger of a serious and permanent injury to their spine, but have surprisingly little pain — even none at all in some cases!
Meanwhile, many non-dangerous problems can cause amazingly severe back pain. A muscle cramp is a good analogy — just think about how painful a Charley horse is! Regardless of what’s actually going on in there, muscle pain is probably the main thing that back pain patients are feeling. The phenomenon of trigger points — tiny muscle cramps, basically11 — could be the entire problem, or a complication that’s more painful and persistent than the original problem. It’s hard to overstate how painful trigger points can be, but they are not dangerous to anything but your comfort.
Two back pain situations you should take seriously right away, no delay
These two back pain scenarios might be medical emergencies. They do not necessarily mean something horrible is wrong, but it’s extremely important to make sure.
- incontinence and/or true numbness around the groin and buttocks in a “saddle” pattern12
- any accident with forces that may have been sufficient to fracture your spine13
If you are experiencing true numbness14 around the groin and buttocks and/or failure of bladder or bowel control, please consider it a serious emergency — do not wait to see if it goes away. These symptoms indicate spinal cord injury or compression15 and require immediate medical attention. (Few people will have symptoms like this without having already decided it’s an emergency, but I have to cover all the bases here.)
And, of course, if you’ve had an accident with forces that may have been sufficient to fracture your spine, please seek thorough medical assessment promptly, including an X-ray to look for a fracture. You need an X-ray to ensure that your spine is not actually broken.
Isn’t it rather obvious that a potential spinal fracture is an emergency?
You’d think so. But consider this story of a motorcycle accident: many years ago, a friend hit a car that had pulled out from a side street. He flew over the car & landed on his head. Bystanders showed their ignorance of spinal fracture by, yikes, carelessly moving him. In fact, his thoracic spine was significantly fractured … yet the hospital actually refused to do an X-ray because he had no obvious symptoms of a spinal fracture. Incredible! The next day, a horrified orthopedic surgeon ordered an X-ray immediately, confirming the fracture & quite possibly saved him from paralysis.
The Big Three signs that you should investigate for an ominous cause of persistent low back pain (but it’s not an emergency)
You shouldn’t worry about low back pain until three conditions have been met:
- it’s been bothering you for more than about 6 weeks16
- it’s severe and/or not improving, or actually getting worse
- there is at least one other “red flag” (see more list items below)
The presence of the big three does not confirm that something horrible is going on. It only means that you need to check carefully.
Andy Whitfield as Spartacus
At his physical peak, not long before getting sick. The first sign of his cancer was steadily worsening back pain. He may have already been in pain at this time.
The story of actor Andy Whitfield is a disturbing and educational example of a case that met these conditions — for sure the first two, and probably the third as well if we knew the details. Whitfield was the star of the hit TV show Spartacus (which is worthwhile, but rated very, very R17). The first sign of the cancer that killed him in 2011 was steadily worsening back pain. It’s always hard to diagnose a cancer that starts this way, but Whitfield was in the middle of intense physical training to look the part of history’s most famous gladiator. Back pain didn’t seem unusual at first, and some other symptoms may have been obscured. Weight loss could have even seemed like a training victory at first! It was many long months before he was diagnosed — not until the back pain was severe and constant. A scan finally revealed a large tumour pressing against his spine.
Don’t confuse threat and risk. Working at the edge is a risk. But then again, so is walking out your front door.
All the red flags for ominous causes of back pain
“Red flags” are signs or symptoms that something medically ominous may be going on. Red flags are not reliable, and their presence is not a diagnosis. When you have some red flags, it only indicates a need to look more closely. Sometimes red flags are missing there really is something serious going on … and sometimes they are a false alarm.18 Check off all that apply … hopefully none or few or only the least alarming of them!
- The risk of an ominous cause for low back pain is generally higher if you are under 20 or over 55. (Andy Whitfield was a tragic exception.)
- Light tapping of the spine is painful.
- Unexplained fever or chills.
- Pain in the upper back is associated with a greater cancer risk.
- Weight loss is particularly a potential sign of cancer.
- Steroid use, other drug abuse, and HIV are all risk factors.
- If you are generally feeling unwell in addition to having low back pain, this may be an indication that a disease process is underway.
- Indicators of autoimmune disease include a family history of autoimmune disease, gradual but progressive increase in symptoms before the age of 40, marked morning stiffness, pain in other joints as well as the low back, rashes, difficult digestion, irritated eyes, and discharge from the urethra.
- Symptoms that spread equally into both legs, especially numbness and/or tingling and/or weakness, and especially if it is aggravated by lifting. The same symptoms limited to one side are also a concern, but less so.
- Difficulty urinating, incontinence, numbness around the groin, foot drop (a toe that drags), and significant weakness in the legs are all potentially serious signs of a neurological problem. These symptoms can develop over time, so it’s important to keep considering them.
Some of these red flags are much less red than others, especially depending on the circumstances. For instance, “weight loss” is common and often the sign of successful diet! (Well, at least temporarily successful, anyway. 😃) Obviously, if you know of a harmless reason why you have a red flag symptom, it isn’t really a red flag (duh!). But every single actual red flag — in combination with severe low back pain that’s been going on for several weeks — is definitely a good reason to get yourself checked out.
Most people who check off an item or two will turn out not to have an ominous cause for their low back pain. But why not check?
The tricky one:
Cancer as a cause of low back pain, and the necessity of testing “just in case” when the symptoms justify it
Sorry I have to use the C word — I know it’s kind of a bummer. But C happens.
A few cancers in their early stages can be hard to tell apart from ordinary back pain — a bone cancer in the vertebrae, for instance — and these create a frustrating diagnostic problem. They are too rare for doctors to inflict cancer testing on every low back pain patient “just in case.” And yet the possibility cannot be dismissed, either! It’s an unsolveable problem.
Most cancers and ominous problems will inevitably start to cause other, distinctive, ominous symptoms, and it won’t be long before someone catches on that there’s more going on than just back pain. So it truly is an extraordinary circumstance for back pain to be ominous without causing other symptoms that raise the alarm.
Meanwhile, it’s extremely common for non-life-threatening low back pain to be alarmingly severe and persistent — to have a loud bark! Your doctor may not appreciate how true this is, and may over-react to all persistent low back pain, even without other red flags. In most cases, you shouldn’t let them scare you. Being “freaked out” about persistent back pain is the real threat: it can make low back pain much worse, and much more likely to last even longer (a tragic irony).
This is an unholy combination of factors: the exact same symptoms can have either an extremely rare but serious cause, or an extremely common but “harmless” cause that can be greatly aggravated by excessive alarm!
The good news is that it’s easy enough to diagnose cancer if you look for it, so the answer to the dilemma is to simply do the testing when the time is right, but not before. There’s every reason to screen for cancer when the conditions merit it — that is, when the red flags appear in combination with persistent, severe pain.
My favourite epitaph: “I told you I was sick!”
Is lower right back pain worrisome?
Pain on the right side of the back is not particularly worrisome, no. Same with the left. There are two main kinds of back pain that occurs only on one side:
- Back pain that could occur on either side, but just happens to be on the right or the left exclusively. This is very common. Most ordinary back pain dominates one side of the back.
- Back pain that comes specifically from structures that exist only on one side. This is a small category.
Most of the anatomy of the low back and abdomen is symmetrical. Some of the guts are not symmetrical, and only some of those is a plausible cause of right-sided back pain. Here’s some of the key anatomy to consider:
- Bones & muscle — All the musculoskeletal structures of the low back are 100% symmetrical, except for small local variations. Injury, pathology, and developmental can occur more one side of course. For instance, intervertebral discs rarely bulge exactly in the centre, but to one side or the other.
- Kidneys — The kidneys are a matched pair. One painful kidney can cause back pain on one side or the other. Kidney pain can feel like back pain, and may occur on only one side. It is usually quite lateral, and just barely low enough to qualify as “low” back pain. However, when kidney stones descend through the ureters, they can cause (terrible) pain in the low back. Kidney stone pain is often so severe and develops so rapidly that it isn’t mistaken for a back pain problem.
- Aorta — The aorta is the largest artery in the body. It descends from the heart through the rib cage and along the left side of the spine. An aortic aneurysm can cause pain on the left side of the back.
- Appendix — The appendix is one of the few clearly one-sided structures in the region. It is on the right. However, appendicitis rarely causes back pain (or at least not without a great deal of abdominal pain as well).
- Intestines — The intestines are a mostly symmetrical mess of tubes, with an equal chance of causing pain on either side — but almost exclusively abdominal pain, not back pain.
- Gall bladder — The gall bladder is on the right. Gall bladder pain can be felt in the back. However, it is usually quite high — even the shoulder blade — and almost always overshadowed by abdominal pain.
- Pancreas — The pancreas is roughly central, and conditions affecting it can cause pain in the mid-back on either side, but usually fairly central. As with all the other viscera, abdominal pain is more likely and likely to be more prominent.
- Spleen — The spleen is on the left, and when it hurts it usually comes with a feeling of fullness and vague pain “somewhere” in the upper left abdomen and the upper part of the low back.
The side of the pain on its own doesn’t tell us much, and most of the one-sided sources of pain are viscera that usually cause abdominal pain instead of back pain, or in addition to it. In other words, the only reason to worry about right or left lower back pain is if it is otherwise worrisome: if you have other red flags or significant non-back symptoms.

What’s new in this article?
Eleven updates have been logged for this article since publication (2009). All PainScience.com updates are logged to show a long term commitment to quality, accuracy, and currency. more
When’s the last time you read a blog post and found a list of many changes made to that page since publication? Like good footnotes, this sets PainScience.com apart from other health websites and blogs. Although footnotes are more useful, the update logs are important. They are “fine print,” but more meaningful than most of the comments that most Internet pages waste pixels on.
I log any change to articles that might be of interest to a keen reader. Complete update logging of all noteworthy improvements to all articles started in 2016. Prior to that, I only logged major updates for the most popular and controversial articles.

In this study, one patient with sciatica was sent for ten MRIs, which produced 49 distinct “findings,” 16 of them unique, none of which occurred in all ten reports. On average, each radiologist made about a dozen errors, seeing one or two things that weren’t there and missing about ten things that were. Yikes.

- People routinely have no pain despite the presence of obvious arthritic degeneration, herniated discs, and other seemingly serious structural problems like stenosis and spondylolistheses. This surprising contradiction has been made clear by a wide variety of research over the years, but the most notable in recent history is Brinjikji 2015. There are painful spinal problems, of course — which was also shown by Brinjikji et al in a companion paper — but they are mostly more rare and unpredictable than most people suspect, and there are many fascinating examples of people who “should” be in pain but are not, and vice versa. Spinal problems are only one of many ingredients in back pain. BACK TO TEXT

This Australian study concluded that “prognosis is moderately optimistic for patients with chronic low back pain,” contradicting the common fear that any low back pain that lasts longer than 6-9 weeks will become a long-term chronic problem. This evidence is the first of its kind, a rarity in low back pain research, a field where almost everything has been studied to death. “Many studies provide good evidence for the prognosis of acute low back pain,” the authors explain. “Relatively few provide good evidence for the prognosis of chronic low back pain.”
Their research differs from past studies of chronic low back pain, which tended to focus on patients who already had a well-established track record of long-term problems (in other words, the people who had already drawn the short straw before they were selected for study, and are likely to carry right on feeling rotten). Instead they studied new cases of chronic low back pain, and found that “more than one third” recovered within nine more months. This evidence is a great foundation for more substantive and lasting reassurance for low back pain patients.BACK TO TEXT
- Back “spasms” are a largely a myth — there’s no such thing a sustained painful contractions of muscles in otherwise healthy people (see Cramps, Spasms, Tremors & Twitches) — but the kernel of truth in the idea of “spasms” may be the idea of trigger points, which are hypothetical “micro cramps,” tiny patches of painfully contracting muscle. Although this idea is controversial, it is nevertheless one of the most likely explanations for common aches and pains that mostly stick to one area (especially the back) and have no other obvious cause.

The big idea of classification-based cognitive functional therapy (CB-CFT or just CFT) is that most back pain has nothing to do with scary spinal problems and so the cycle of pain and disability can be broken by easing patient fears and anxieties. For this study, CFT was tried with 62 patients and compared to 59 who were treated with manual therapy and exercise. The CFT group did better: a 13-point boost on a 100-point disability scale, and 3 points on a 10-point pain scale. As the authors put it for BodyInMind.org, “Disabling back pain can change for the better with a different narrative and coping strategies.” These results aren’t proof that the confidence cure works, but they are promising.The Mind Game in Low Back Pain.

Why is back pain still a huge problem? Maybe this: “It is extremely difficult to alter the potentially disabling belief among the lay public that low back pain has a structural mechanical cause. An important reason for this is that this belief continues to be regularly reinforced by the conditions of care of a range of ‘hands-on’ providers, for whom idiosyncratic variations of that view are fundamental to their professional existence.”
Well said. If only I could edit it, though, I would say that it is difficult to alter that belief in anyone, patient or professional. The belief isn’t just reinforced by the practices of manual therapists, it’s the reason for them.BACK TO TEXT
- The complete list, from Low Back Pain: Clinical Practice Guidelines:
In the vast majority of patients with low back pain, symptoms can be attributed to nonspecific mechanical factors. However, in a much smaller percentage of patients, the cause of back pain may be something more serious, such as cancer, cauda equina syndrome, spinal infection, spinal compression fractures, spinal stress fractures, ankylosing spondylitis, or aneurysm.BACK TO TEXT

Marvelously progressive, concise, and cogent guidelines for physicians on the treatment of low back pain. These guidelines almost entirely “get it right” in my opinion, and are completely consistent with recommendations I’ve been making for years on PainScience.com. They are particularly to be praised for strongly discouraging physicians from ordering imaging tests only “for patients with low back pain when severe or progressive neurologic deficits are present or when serious underlying conditions are suspected.”BACK TO TEXT
- Or anything else. Pain is a poor indicator, period! The human nervous system is really terrible about this: it routinely produces false alarms, and alarms that are much too loud.

- There is controversy and scientific uncertainty about trigger points. It’s undeniable that mammals suffer from sensitive spots in our soft tissues … but their nature remains unclear, and the “tiny cramp” theory could be wrong. The tiny cramp theory is formally known as the “expanded integrated hypothesis,” and it has been prominently criticized by Quintner et al (and not many others). However, it’s the mostly widely accepted explanation for now. BACK TO TEXT
- That is, the parts of your body that touch a saddle when riding a horse: groin, buttock, and inner thighs. I experienced rather intense, terrifying awareness of symptoms in this area in the aftermath of my wife’s car accident in early 2010. With a mangled T12 vertebrae, she was at real risk of exactly this problem. Fortunately, she escaped that quite serious problem. But, sheesh, I was vigilant about it for a while! “Honey, any numbness in your saddle area today?” BACK TO TEXT
- Example: a friend of mine went to the hospital after a motorcycle accident. He’d flown over a car and landed hard on his head. Bizarrely, he was sent home with very little care, and no imaging of his back, even though he was complaining of severe lower back pain. A doctor reassured him that it was just muscle spasms. (This all happened at a hospital that was notorious for being over-crowded and poorly run.) The next day, still in agony, he went to see a doctor at a walk-in clinic, who immediately took him for an x-ray … which identified a serious lumbar fracture and imminent danger of paralysis. He had been lucky to get through the night without disaster! He was placed on a spine board immediately and sent for surgery. The moral of the story? Sometimes, when you’ve had a major trauma and your back really hurts, it’s because your back is broken. BACK TO TEXT
- True numbness is not just a dead/heavy feeling (which is common, and caused even by minor muscular dysfunction in the area), but a significant or complete lack of sensitivity to touch. You have true numbness when you have patches of skin where you cannot feel light touch. Such areas might still be sensitive to pressure: you could feel a poke, but as if it was through a layer of rubber. Most people have experienced true numbness at the dentist. BACK TO TEXT
- The condition is cauda equina syndrome. It involves “acute loss of function of the neurologic elements (nerve roots) of the spinal canal below the termination (conus) of the spinal cord,” where the nerves spread out like a horse (equina) tail.

- This standard recommendation reinforces the alarming idea that low back pain that lasts longer than a few weeks is Really Bad News. It’s not. It’s a clue. It’s a reason for concern and alertness. But many cases of low back pain that last for 6 weeks will still go away. Once again, see the 2009 research published in the British Medical Journal, which showed that more than 30% of patients with “new” chronic low back pain will still recover without treatment.

Premkumar et al present evidence that the traditional “red flags” for ominous causes of back pain can be quite misleading. The correlation between red flags and ominous diagnoses is poor, and prone to producing false negatives: that is, no red flags even when there is something more serious than unexplained pain going on. In a survey of almost 10,000 patients “the absence of red flag responses did not meaningfully decrease the likelihood of a red flag diagnosis.“ This is not even remotely a surprise to anyone who paid attention in back pain school, but it’s good to have some harder data on it.BACK TO TEXT
