Sometimes we feel a bit cruddy and sore after a massage, like it was a big workout. Post-massage soreness and malaise (PMSM) is embraced as a minor side effect and hand-waved away by almost everyone as some kind of no-pain-no-gain thing.
But it can be much harsher.
Massage is not “detoxifying” in any way (that’s pseudoscientific nonsense). But it might be the opposite, ironically: PMSM may be caused by mild RHABDOMYOLYSIS, a kind of poisoning related to injury.
True rhabdo is a medical emergency in which the kidneys are gummed up by myoglobin from crushed muscle. But tamer rhabdo can be caused by physical stress, even just intense exercise (that’s a medical reality, see exertional or “white collar” rhabdo) … and quite possibly “deep tissue” massage as well, which is still just a hypothesis.
That hypothesis is getting more evidence-based. There are some good formal case studies, and I have many informal ones: many people find this article and send me reports of post-massage rhabdo signs/symptoms. The phenomenon of PMSM needs explaining, and rhabdo is surprisingly good candidate. There is plenty of plausibility and empirical “smoke” to support the hypothesis.
And what if it’s true? A very NASTY side effect, disturbingly at odds with faith in the value of strong massage.
Mild PMSM also has several possible non-rhabdo explanations, like coincidental mild illness, pathological vulnerability, and psychologically disarming our normal psychological defenses. (No, a Jarisch-Herxheimer reaction is NOT a plausible explanation.)
I have much more detail on this topic, see article link in the comments.

P.S. You can’t “flush” the rhabdo (or anything else) away with massage or by drinking a little extra water.
