Save Yourself from Shin Splints!

The term “shin splints” has multiple personality disorder: it might refer to nearly any of several problems that cause shin pain, depending on what you read or who you talk to. This extremely detailed tutorial aims to help readers, both professionals and patients, with all the different shin pain problems that get stuck with the label “shin splints.” All of these things (at least) are the “real” shin splints:

• compartment syndrome
• medial tibial stress syndrome
• tibial stress fracture

People often mistakenly believe that the real shin splints is limited to just one of these. For instance, medial tibial stress syndrome — irritation and degeneration of the shin bone, and/or the soft tissue around it — is probably what most professionals think shin splints is these days, and it probably is the most common type of shin pain. But it is definitely not the only kind.

The confusion about the naming of shin pain probably can be traced to the truly deep and cosmic mysteries that surround shin pain. Many cases defy easy classification. Either they seem to possess the symptoms of several different problems, or they actually are more than one problem.6 Many scientific studies of shin pain have created more questions than they answered. Diagnosis and treatment can be difficult, and some cases of shin splints are almost freakishly severe.

This tutorial thoroughly explores every common type of shin pain: the kinds of tissue failure involved, surprising scientific controversies and mysteries, plus the most neglected and underestimated factors in shin pain, crucial to understanding many difficult cases.

 

The tibialis anterior muscle of the shin usually contains significant myofascial trigger points (muscle knots) — an under-diagnosed & under-treated factor in many cases of shin pain.

Sports medicine in general is amazingly primitive considering how much potential funding it has. You’d think anything affecting elite athletes with huge audiences would be getting more attention! The situation is improving, but only recently and it still has a long way to go.7

And there are certainly no “shinologists.” Feet have entire professions devoted to them, but not shins! For most professionals, shin pain is just one of a list of hundreds of common pain problems they deal with, and they are more or less completely unaware of the finer points of the subject, particularly recent scientific research. A typical orthopedics text devotes only a paragraph to shin pain; most web pages are brief and crappy, barely scratching the surface of the topic.8 And so, in many cases the only thing professionals know is quarter-century old conventional wisdom. Such large gaps in professional knowledge make it tough for patients to find competent help for more severe and stubborn cases of shin pain. There are several shin splints issues that doctors and therapists are particularly uninformed about, and often fail to consider:

1. Unfortunately, many pros do not appreciate how dangerous acute compartment syndromes are, and often fail to recognize them and give appropriate warnings to patients.
2. Tissue fatigue is a critical shin splints concept, and yet the majority of professionals have rarely or never thought of it in this way, especially thinking only in terms of relatively simplistic biomechanical stresses rather than the more subtle and complicated biological vulnerabilities and the weirdness of chronic pain that are more important.9
3. Progressive rehab is a sound principle — the heart of all injury recovery — but it is often rushed, and the importance of initial resting seriously underestimated and poorly handled. Often the only problem with a rehab plan is that it was started too aggressively.
4. Muscle pain is probably a significant factor in many cases of shin pain, but this is almost always missed or underestimated — health care has a huge blind spot for muscle, and often just ignores the role of muscle in injuries.10

Until you feel confident that you know which type of shin pain you have, you should assume the worst and avoid aggravating the condition. Why?

Compartment syndrome — high-pressure swelling, fluid that’s trapped in a limb — is one kind of tissue failure that mostly afflicts lower legs.11 It’s extremely dangerous when acute. Compartment syndrome involves a vicious cycle which is not necessarily self-limiting (as many other injuries are). Once it starts, it may spiral out of control and literally kill the affected muscles, causing permanent deformity and disability at the very least, and even risk lethal infection. Triple yikes! This is absolutely serious, and unlike most other athletic injuries.

Although the pain is usually severe enough to stop people from running, some athletes may be foolhardy enough to try to keep going — if this is you, please stop! Rapidly worsening shin or calf pain absolutely must be treated like a medical emergency, and not just a cramp on your style. You are in danger of destroying your athletic career!

Compartment syndrome was Ken Hildebrand’s worst injury after being trapped for four days under an ATV. “My leg swelled up about four times the size of normal,” Hildebrand said.

Ken Hildebrand of Alberta, Canada, knows just how serious compartment syndrome can be. On January 8, 2008, Mr. Hildebrand was pinned under an all-terrain vehicle in the Rocky Mountains. He survived for 96 hours by eating rotting animal carcasses, drinking melted snow, fending off coyotes with a whistle, and thinking of his grandchildren.

But compartment syndrome was his worst problem!

My leg swelled up about four times the size of normal. And in order for blood to get through they have to slice the muscle so that it can drain and then they slowly let it repair itself. The leg is good now, I'm going to be able to keep the leg, but the foot is still iffy.

Ken Hildebrand on “As It Happens,” CBC Radio One, January 23, 2008

In Mr. Hildreband’s case, compartment syndrome was the consequence of trauma, and he suffered a particularly severe case of compartment syndrome, with extreme swelling. However, equally dangerous consequences are possible in runners who try to “run through the pain.” So don’t!

Reassuring concluding note: chronic compartment syndromes, by contrast, are relatively safe — frustrating and uncomfortable, but much less dangerous. Shin or calf pain that has been around for a while and isn’t rapidly worsening is pretty unlikely to be a serious problem.

 

Acute compartment syndrome is no joke

To treat acute compartment syndrome, the muscle compartment is sliced open to relieve the pressure. Tissue bulges like a hot sausage spilling out of its casing. The result is a massive surgical wound that takes months to heal & leaves substantial scarring.

Runners with “perfectionist tendencies” are 17 times more likely to get injured, which seems rather odd and suspiciously psychological. Stress fractures aren’t psychosomatic … right? It’s not that kind of stress! “Still, for anyone who’s been around runners,” says sports science journalist Alex Hutchinson, “it’s not hard to believe that there are some personality traits that are associated with injury risk.”12 Indeed.

It’s probably just that perfectionists push themselves harder. Perfectionism is a proxy for stereotypical athletic ambition: intense, driven, a bit reckless, likely to ignore warning signs.

There’s only one major risk factor for shin pain is known with any confidence:

1. excessive loading

But it’s definitely not just that. First of all, not all loading is physical or simple.13 Shin splints is routinely defined as an overload, overuse, or exercise-induced problem, and this is correct — but it’s also not the whole story. Not every case of shin splints involves tissue overloading, but most probably do. And not every case of shin splints only involves tissue overload.

There are deep mysteries about why shin splints happen to some people and not others, and in which tissues it is actually affecting and how. Tissue fatigue has clinical implications that are often underestimated (and which make up a good part of this tutorial). Despite their willingness to define shin splints as mainly a tissue fatigue problem, few professionals are willing to actually study it or treat it that way. If overuse is the primary problem, then rest is probably the highest priority in recovery — but rest tends to be marginalized and underestimated as a treatment option, in favour of a wide array of “fancier” theories and therapies, mostly aimed at “correcting” alleged non-obvious sources of physical stress …

GO TO TOP • CONTENTS • END • NOTES • BOTTOM

There is considerable scientific controversy and confusion about the other risk factors and stresses that might cause or contribute to shin splints. They particularly include a wide variety of biomechanical problems — all kinds of anatomical, gait and postural issues, basically all concerned with one kind of “crookedness” or another — factors that are supposedly significant according to one expert or another, but which may or may not actually be. Such as (these are just a few examples)…

Testimonials on health care websites reek of quackery, so publishing them has always made me a bit queasy. But my testimonials are mostly about the quality of the information I’m selling, and I hope that makes all the difference. So here’s some highlights from the kind words I’ve received over the years … plus some of the common criticisms I receive, at the end. These are all genuine testimonials, mostly received by email. In many cases I withold or change names and identifying details.

Thank you so much for taking the time to put this book together, and in a way that makes it feel like you wrote it just for me! You have a great writing style.

~Chyna Pittman

Thanks for the great tutorial! Much more helpful than any of the professionals I’ve seen for my chronic running-induced shin pain — all the doctors, sports massage therapists, chiropractors, and physical therapists!

~Cassandra Clarke

I was so sick of reading crappy little articles with the same old advice. Seems like there’s about ten thousand that all say the same useless things. Thanks for the deep dive!

~Sandra Frank, Ottawa, Ontario

A year of shin pain and hardly anything but painkillers and ultrasound from doctors and physios. I was giving up! I thought I’d never have a nice long walk again. Actually I was even more discouraged after reading this book, because so many treatments are apparently bullshit. But then I started experimenting with some of the massage ideas, and bam! The nightmare ended! Unbelievable!

~Alison Fromer, “just a serious walker”

My shin pain has been very stubborn. I know as well anyone there’s no easy way to deal with this, and this book confirmed that! But I really appreciate the education. Even after a couple years of dealing with shin splints, I still had a bunch of nagging questions that this book really helped to clear up. That alone was worth the price, but there were also a couple rehab ideas I’d never come across. Totally worth it.

~Andy Flaco, New York runner

One more noteworthy endorsement, with regards to this whole website and all of my books, submitted by a London physician specializing in chronic pain, medical education, and patient-advocacy (that’s a link to his excellent blog):

I’m writing to congratulate and thank you for your impressive ongoing review of musculoskeletal research. I teach a course, Medicine in Society, at St. Leonards Hospital in Hoxton. I originally stumbled across your website whilst looking for information about pain for my medical students, and have recommended your tutorials to them. Your work deserves special mention for its transparency, evidence base, clear presentation, educational content, regular documented updates, and lack of any commercial promotional material.

— Dr. Jonathon Tomlinson, MBBS, DRCOG, MRCGP, MA, The Lawson Practice, London

What about criticism and complaints?

Oh, I get those too! I do not host public comments on PainScience.com for many reasons, but emailed constructive criticism, factual corrections, requests, and suggestions are all very welcome. I have made many important changes to this tutorial inspired directly by critical, informed reader feedback.

But you can’t make everyone happy! Some people demand their money back (and get it). I have about a 1% refund rate (far better than average in retail/e-commerce). The complaints of my most disatisfied customers have strong themes:

• Too negative in general. Some people just can’t stomach all the debunking. Such customers often think that I dismiss “everything” … which I disagree with.
• Too negative specifically. Some are offended by about a treatment option that they personally use and like. Or sell.
• Too advanced. Although I work hard to “dumb” the material down, quite a few people still just find it too dense and dorky.
• Too simple. Some people think they already know everything about the topic. Maybe they do, and maybe they don’t. I always wish I could give these readers a pop quiz. 😉 In my experience, all truly knowledegable people get that way by embracing every new persective and source of information.

Thanks to every reader, client, and book customer for your curiosity, your faith, and your feedback and suggestions, and your stories most of all — without you, all of this would be impossible and pointless.

Writers go on and on about how grateful they are for the support they had while writing one measly book, but this website is actually a much bigger project than a book. PainScience.com was originally created in my so-called “spare time” with a lot of assistance from family and friends. Thanks to my wife for countless indulgences large and small; to my parents for (possibly blind) faith in me, and much copyediting; and to friends and technical mentors Mike, Dirk, Aaron, and Erin for endless useful chats, repeatedly saving my ass, plus actually building many of the nifty features of this website.

Special thanks to some professionals and experts who have been particularly inspiring and/or directly supportive: Dr. Rob Tarzwell, Dr. Steven Novella, Dr. David Gorski, Sam Homola, DC, Dr. Mark Crislip, Scott Gavura, Dr. Harriet Hall, Dr. Stephen Barrett, Dr. Greg Lehman, Dr. Jason Silvernail, Todd Hargrove, Nick Ng, Alice Sanvito, Dr. Chris Moyer, Lars Avemarie, PT, Dr. Brian James, Bodhi Haraldsson, Diane Jacobs, Adam Meakins, Sol Orwell, Laura Allen, James Fell, Dr. Ravensara Travillian, Dr. Neil O’Connell, Dr. Tony Ingram, Dr. Jim Eubanks, Kira Stoops, Dr. Bronnie Thompson, Dr. James Coyne, Alex Hutchinson, Dr. David Colquhoun, Bas Asselbergs … and almost certainly a dozen more I am embarrassed to have neglected.

I work “alone,” but not really, thanks to all these people.

I have some relationship with everyone named above, but there are also many experts who have influenced me that I am not privileged to know personally. Some of the most notable are: Drs. Lorimer Moseley, David Butler, Gordon Waddell, Robert Sapolsky, Brad Schoenfeld, Edzard Ernst, Jan Dommerholt, Simon Singh, Ben Goldacre, Atul Gawande, and Nikolai Boguduk.

2011 — Update: Now cautiously endorsing Oesh shoes. [Section: Hitting the road: shoes, surfaces, impact, and the spring in your step.]

2011 — Major update: Major improvements to the table of contents, and the display of information about updates like this one. Sections now have numbers for easier reference and bookmarking. The structure of the document has really been cleaned up in general, making it significantly easier for me to update the tutorial — which will translate into more good content for readers. Care for more detail? Really? Here’s the full announcement.

2011 — New section: Another substantial addition to the tutorial, the third in recent history. [Section: Hitting the road: shoes, surfaces, impact, and the spring in your step.]

2011 — New section: Another beefy new section for this tutorial, the second addition lately. [Section: Stripping: a popular massage techique for the shins.]

2011 — New section: Finally, long overdue, a new section on this topic (for all the running injury tutorials). [Section: Should you run naked? On faddish running styles and running shoes (or the lack thereof).]

2011 — Important new info: Where’s the fire? Recently I published a major new article about repetitive strain injuries, in which I explain that these injuries are rarely actually inflamed. Instead of being “on fire,” excessively stressed tissues tend to break down without inflammation — a kind of rot. For the full scoop on inflammation and repetitive strain injuries, see: Repetitive Strain Injuries Tutorial: Five surprising and important facts about repetitive strain injuries like carpal tunnel syndrome, tendinitis, or iliotibial band syndrome.

2010 — Minor upgrade: Upgrade to the description of popliteal artery entrapment syndrome (PAES), which is often confused with compartment syndromes. [Section: A more detailed looked at the four most common types of shin pain.]

2010 — Minor upgrade: Repaired an alarmingly large batch of typographic errors. Amazing what slips through!

2010 — New cover: At last! E-book finally has a “cover.”

2010 — Minor update: Added results of a study of surgery for stress fractures in elite dancers. [Section: Surgery for shin pain.]

2009 — New section: An important new section on anti-inflammatory medications, notably including discussion of Voltaren® Gel, a worthwhile treatment option for shin splints only recently got into my radar. You can read about Voltaren in a free article as well as here in the tutorial, but the tutorial covers the topic specifically as it relates to each of the different kinds of shin splints. [Section: You and “vitamin I”: anti-inflammatory meds, especially Voltaren® Gel.]

2009 — Major upgrade: Major miscellaneous improvements to the section today. [Section: Stretching is probably mostly ineffective for all kinds of shin splints.]

2009 — Minor update: Added nutraceuticals to the section. [Section: Brief debunkery of several other therapies that you should be skeptical of.]

2009 — New section: Starting off with just a few items. More will be added in time, but there’s four good ones to start. [Section: Brief debunkery of several other therapies that you should be skeptical of.]

2009 — New section: No notes. Just a new section. [Section: Diagnosis: How do you know which kind of shin splints you’ve got?]

2009 — Huge upgrade: About a dozen new sections, many more footnotes, and widespread editing for clarity and thoroughness. Today this tutorial is now officially “extremely detailed,” like the other advanced tutorials on PainScience.com, and went up for sale.

2009 — New section: New section to explain and highlight evidence from Gaeta about the high prevalence of microscopic bone damage found in long-distance runners. [Section: MRI and CT scanning may be helpful.]

2009 — New section: No notes. Just a new section. [Section: Bone tired: medial tibial stress syndrome is probably about bone fatigue, not inflamed soft tissue.]

2009 — New section: No notes. Just a new section. [Section: Strengthening is probably also a completely ineffective therapy.]

2008 — Major upgrade: Several major revisions and corrections.

2008 — Update: Added colorful anecdote from the Canadian wilderness to illustrate the seriousness of acute compartment syndrome. [Section: Danger! Please do not try to run through shin splints! Acute compartment syndrome can be extremely dangerous!]

2007 — Major update: Clarified diagnostic information significantly by integrating important information gleaned from Edwards et al [Section: A diagnostic algorithm (you know it’s good if it’s an “algorithm”).]

8. In 2010, the Journal of Bone & Joint Surgery reported that “the quality and content of health information on the internet is highly variable for common sports medicine topics,” such as knee pain and low back pain — a bit of an understatement, really.

    Alex speculates:

    Do perfectionists simply train harder, and get injured more as a result? If so, it’s possible that their lofty goals produce faster race times despite the heightened injury risk, in which case it’s not clear this is a problem. But it’s also possible that perfectionists are more susceptible to bad training decisions—refusing to take a day off in the early stages of an injury, or ramping up training more quickly than their body can handle.

Paying in your own (non-USD) currency is always cheaper! My prices are set slightly lower than current exchange rates, but most cards charge extra for conversion.

Example: as a Canadian, if I pay $19.95 USD, my credit card converts it at a high rate and charges me $26.58 CAD. But if I select Canadian dollars here, I pay only $24.95 CAD.

Why so different? If you pay in United States dollars (USD), your credit card will convert the USD price to your card’s native currency, but the card companies often charge too much for conversion — it’s a way for them to make a little extra money, of course. So I offer my customers prices converted at slightly better than the current rate.
