I have been expanding and upgrading this website for 20 years now, and full-time since 2010. Useful new references are added almost daily. I am always working on an endless list of improvements, and corrections and mea culpas are always the highest priority items. This page lists everything that’s new or changed lately … or just Google for content that’s new in the last month or year. ~ Paul Ingraham, PainSci Publisher

The last 60 updates to featured articles and tutorials
Like good footnotes, update logging sets PainScience.com apart from most other health websites and blogs. It’s fine print, but important fine print, in the same spirit of transparency as the editing history available for Wikipedia pages. I log any change to articles that might be of interest to a keen reader.
Current Update Stats — 60 updates to 31 articles & books in 208 days, breaking down into 23 major updates, 21 medium, 15 minor. That’s every 3.5 days in recent history; there have been 1688 updates since comprehensive logging started in mid-2016 ?Comprehensive update logging started in the summer of 2016. Prior to that, I only logged major updates for the most popular and controversial articles. (about one every other day) … plus very roughly ten thousand more since the early 2000s. See the complete update archives.
showing of 60 recent updates
S | Mar 16 | Chronic Pain and Inequality — Science update: cited Boyd on poor demographic reporting and representation in pain research. |
L | Mar 5 | The Complete Guide to Patellofemoral Pain Syndrome — New chapter, self-exam for patellofemoral joint tenderness. |
M | Mar 4 | The Complete Guide to Trigger Points & Myofascial Pain — Science update, Botox injection — There is no significant new evidence, but the chapter was missing some significant old evidence. I added that, and did some general editing and revising while I was at it. Bottom line unchanged. |
M | Mar 3 | Painful Lessons — Added two new items: “Pain is mainly a function of complex and messy physiology,” and “Quackery and crankery is the rule for chronic pain treatment, not the exception.” Elaborated on “the science is a mess.” |
M | Mar 1 | Reviews of Pain Professions — Added “Manual therapy (a category of professions).” |
S | Mar 1 | Manual Therapy: What is it, and does it work? — Substantial editing, with particularly meticulous improvements to the article summary, which is widely reproduced wherever relevant around the site. “Integration” with the rest of the library is a standard production step for all articles — linking to and from other articles — but it was particularly extensive here, because the topic is so important to PainScience.com as a whole. There are many dozens of appropriate places to summarize manual therapy, or some aspect of it, and link to more information, so it was very important to have a highly polished summary. |
M | Feb 29 | Whole Body Cryotherapy for Pain — Added a few citations. More detail and polish throughout the article. |
M | Feb 28 | A Historical Perspective On Aches ‘n’ Pains — General improvements and modernization. I particularly fleshed out the “new” section (from 6 years ago!) about why “poor quality healthcare for chronic pain and injury is still the rule.” |
M | Feb 27 | Painful Lessons — Added more thoughts about how skepticism goes wrong, and the accessibility and importance of resistance training. |
S | Feb 26 | The Complete Guide to Chronic Tension Headaches — Added detail, chinook headaches — Added some conspicuously missing detail about how cinook headaches work. |
S | Feb 17 | You Might Just Be Weird — Added an item about variants of the shape of nasal passages and sinuses being a plausible explanation for the phenomenon of chinook headaches. |
S | Feb 10 | Massage Therapy Side Effects — Added citation to a case study of a gluteal blood vessel seriously damaged by “deep tissue” massage (see Sun). Also added a fairly substantive footnote about the reaction this item got on social media. |
L | Feb 9 | The Complete Guide to Patellofemoral Pain Syndrome — New section, gait retraining. |
S | Feb 8 | Tissue Provocation Therapies in Musculoskeletal Medicine — Minor editing. Added a more or less complete list of “provocation therapies,” also serving as a partial table of contents. |
M | Feb 2 | Does Fascia Matter? — Added information, origins section — Discussed naprapathy as a great example of the older, deeper roots of modern fascia pseudoscience. |
M | Jan 31 | Does Posture Matter? — Editing, conclusion — “Just” a bunch of editing and polish. Sometimes that is a “just,” but in this case I actually worked really hard on the language. I’ve been saying this stuff for many years… it deserves a really good summary and mic drop! Also added an image and some supplementary detail. |
L | Jan 22 | Tissue Provocation Therapies in Musculoskeletal Medicine — I shared a quote from this article about scraping massage, and it was extremely popular, so I decided to do a wave of updates to this article for the first time in several years. I upgraded the summary, added detail and citations to the eccentric loading section, and added two whole new sections: “The SAID principle: another basic concept in adaptation” and “Is trigger point therapy “provocative”? I also added a more detailed description of the “potency bias.” |
M | Jan 20 | Guide to Repetitive Strain Injuries — Updated citations for the claim that "a lot of regular exercise does not inevitably destroy joints." I added a couple news ones (Voinier, Weng), a couple old ones (Luke, Williams), and improved the annotations. |
M | Jan 19 | Anxiety & Chronic Pain — Extensive improvements to the section, “Reasonable doubt: the special threat of health anxiety (hypochondria).” Nothing of substance has changed, it’s just more and better on an important sub-topic. The section is in this guide’s members-only area, but the section is also available as a free post for a while. I added a new audio version. |
S | Jan 12 | Complete Guide to Plantar Fasciitis — Minor improvements, recommendations round-up — Integrated and updated barefoot running advice, and other minor changes. |
M | Jan 12 | Complete Guide to Plantar Fasciitis — New content, barefoot running effects — Added specific information about the effect of barefoot running on plantar fasciitis, and related minor editing. This chapter now fits in better with the new one about barefoot walking. |
L | Jan 11 | Complete Guide to Plantar Fasciitis — New chapter, barefoot walking. |
S | Jan 3 | Neuropathies Are Overdiagnosed — More and better detail on the over-prescription of anticonvulsants. |
L | Dec 22 | The Complete Guide to Patellofemoral Pain Syndrome — New content, tight IT band chapter — Added a fascinating and extreme case study that perfectly illustrates the potential relationship between ITBS and patellofemoral pain (though still exasperatingly unclear). Includes audio version. |
L | Dec 22 | The Complete Guide to IT Band Syndrome — New content, iliotibial tightness chapter — Added a fascinating and extreme case study that perfectly illustrates the potential relationship between ITBS and patellofemoral pain (though still exasperatingly unclear). Includes audio version. |
L | Dec 20 | The Complete Guide to Patellofemoral Pain Syndrome — Revised and expanded, trigger points chapter — The section had been short and basic for many years, and many readers would never have guessed how much more I’ve written about this topic. It’s now more thorough and more in tune with the times, including the modern skeptical pespective on trigger points, and a more nuanced discussion of what role they might or might not have in patellofemoral pain. |
S | Dec 19 | The Complete Guide to Patellofemoral Pain Syndrome — Minor editing, patellofemoral pain vs ITBS — Just a few little improvements, especially harmonizing with the IT band tightness chapter. |
L | Dec 12 | The Complete Guide to Patellofemoral Pain Syndrome — Many improvements, differential diagnosis — After greatly expanding this chapter in 2022, it was a bit of a mess: thorough but disorganized. I eliminated some egregious rambling (was I drunk?). |
M | Dec 9 | The Complete Guide to Patellofemoral Pain Syndrome — New topic, analgesics chapter — Added a small section: “Be careful what you wish for: pain relief can be problematic.” |
M | Dec 9 | The Complete Guide to Patellofemoral Pain Syndrome — Major revision, intro to diagnosis — I pretty much just started from scratch and re-wrote this chapter. It’s now better in all the ways, I think. |
M | Dec 9 | The Complete Guide to Chronic Tension Headaches — Minor update, cervicogenic headache chapter — Added more detail about occipital neuralgia. |
L | Dec 8 | The Complete Guide to Patellofemoral Pain Syndrome — New section, criteria for discontinuing running. |
L | Dec 8 | The Complete Guide to Patellofemoral Pain Syndrome — New sub-topic, cartilage thickness — Added a substantive new sub-topic: “Built for pressure: How thick is the patellofemoral joint cartilage? And the patella?” |
L | Dec 4 | The Complete Guide to Patellofemoral Pain Syndrome — Evidence update — Updated several references throughout the introductory sections, along with many related edits and improvements. |
M | Dec 2 | The Medical Blind Spot for Aches, Pains & Injuries — Fairly extensive modernization of the article, reflecting substantial evolution in my views over the last decade. |
L | Nov 22 | The Complete Guide to Chronic Tension Headaches — New section. |
M | Nov 22 | The Complete Guide to Chronic Tension Headaches — Minor update, cervicogenic headache chapter — Discussed the special case of occipital neuralgia. |
S | Nov 10 | Cramps, Spasms, Tremors & Twitches — Added hemifacial spasm to the list of examples of pathological contractions. |
S | Oct 30 | Vulnerability to Chronic Pain — Added a little evidence and evidence-informed speculation about the possibility of more short-term anti-inflammatory benefits of a healthier diet. |
L | Oct 30 | Chronic, Subtle, Systemic Inflammation — New section, on junk food as an inflammation driver. |
S | Oct 28 | Marijuana for Pain — Science update about the efficacy and safety of CBD — all bad news, I’m afraid. But it’s not surprising. |
M | Oct 19 | The Complete Guide to Low Back Pain — Revision, MDT review chapter — Just a bunch of miscellaneous revision as I prepared the chapter for publication as an excerpt. |
M | Oct 7 | Neuropathies Are Overdiagnosed — Science update with some substance, a bit more than just a citation: Peet et al really adds to the case that the fraudulent marketing of anticonvulsants was a pain care catastrophe, resulting in extreme over-prescription. |
L | Oct 5 | The Complete Guide to Low Back Pain — New section. |
L | Sep 21 | The Complete Guide to Low Back Pain — Rewritten, back pain as an overuse injury — Like-new re-write. Before: simplistic and old-school by my 2023 standards. After: not very scientifically rigorous, but much more informed and wide-ranging speculation. And kinda fun. |
S | Sep 20 | Marijuana for Pain — Added a citation to Gedin on the role of placebo, poor blinding, and media buzz. |
S | Sep 18 | Ten Trillion Cells Walked Into a Bar — Added a fresh citation (first note) about the number of cells we have: roughly thirty trillion, according to a new paper. |
S | Sep 7 | Opioids for Chronic Aches & Pains — Edited. Made several minor clarifications, most notably emphasizing that opioids are indeed effective for some kinds of chronic pain (despite being surprisingly ineffective for so many others). |
M | Sep 2 | Trigger Point Doubts — Added a very substantial (bloated?) new footnote, in which I (finally) provide my best guesses for “what really happened” in a trigger point therapy success story. There’s also a blog post. |
M | Aug 30 | A Deep Dive into Delayed-Onset Muscle Soreness — A variety of modest improvements to the sections on active recovery, particularly the evidence. |
L | Aug 27 | The Complete Guide to Low Back Pain — New chapter, treating rib subluxations. |
L | Aug 27 | The Complete Guide to Low Back Pain — New chapter, rib subluxations — Not just a new chapter, but a particularly huge one, based on interesting new science, with plenty of value. (PainSci Members can also read this in a recent blog post, “Extra, extra! Extra floating ribs are way more common than anyone knew.”) |
L | Aug 26 | Chronic, Subtle, Systemic Inflammation — Rewritten, psychologically triggered neuroinflammation — Significant revision of all neuroinflammation content. |
L | Aug 26 | Chronic, Subtle, Systemic Inflammation — Rewritten, neuroinflammation dysfunction — Significant revision of all neuroinslammation content. |
L | Aug 26 | Chronic, Subtle, Systemic Inflammation — Rewritten, neuroinflammation with subtle triggers — Significant revision of all neuroinflammation content. |
L | Aug 26 | Chronic, Subtle, Systemic Inflammation — Rewritten, sickness behaviour — Significant revision of all neuroinflammation content. |
L | Aug 26 | Chronic, Subtle, Systemic Inflammation — Rewritten, neuroinflammation intro — Significant revision of all neuroinflammation content. |
S | Aug 25 | The Complete Guide to Patellofemoral Pain Syndrome — Science update, strengthening — Added an important footnote with a bunch of detail about exactly what kind of strength training was tested by Hansen et al.. |
L | Aug 24 | Quite a Stretch — New section, stretching for hypertrophy. |
M | Aug 23 | 38 Surprising Causes of Pain — Added small new section about foreign objects, inspired by a good new example (a bullet embedded in someone's hand for decades before it started to hurt). |

What’s new on this page about new stuff?
Ironically, I’ve actually updated this page quite a few times without logging the change. 😜
May 24, 2023 — An update to the updates page?! It’s so meta! It’s not going to happen often, but I just finished improving the whole update-logging system in several ways. Most of the upgrades are "under the hood," but there is now much better filtering for the update list, and the foundations have been laid for more improvements in the future.
2016 — Publication.
