Exactly. I was so desperate, I would have tried anything. But, I could not finish
The Mindbody Prescription. General non-scientific fluff, and a lot of complaining about Freud not being taken seriously these days. No real evidence, although I only got through a few chapters.
However, despite me thinking the book was rubbish and tossing it shortly, my RSI problems disappeared. I guess the suggestion that pain wasn't actually physical in source was enough for the pain to stop.
I've gone from being dominated by RSI problems to not giving it much thought at all.
The placebo effect is real, sometimes even when the patient is aware that it's a placebo.
Note: I don't think the book is correct. There are plenty of phenomenon that we don't understand, and not having a real explanation is not reason to just make one up and assert its correctness without evidence.
