Blood injection treatment bombs a test
A weekly nugget or two of pain science news and ideas for patients and pros, usually 400–1000 words. The blog is the “director’s commentary” on the core content of PainScience.com: a library of major articles and books about common painful problems and popular treatments. See the blog archives or updates for the whole site.
Utterly unsurprising: injecting your own blood doesn’t help tendinitis. Nice to have a decent new trial about this over-hyped therapy though.

Not many good treatment ideas work as well in practice as they do in theory. The null hypothesis is super reliable.
