While my understanding/explanation might be wrong the result was undeniable: I had terrible RSI and now I don't.
I personally could care less why it happened. All I know is that it happened, and this is what I did to make it happen. Ultimately if it works, it works. And you can't deny in this particular case, that it worked.
If expressing my experience can help at least 1 person, in the same way that someone else had expressed the very same experience to me, then I'll take my chances.
It's still an ok suggestion because at least it's safe and cheap, but you can't really say "it works" with n=1
Given the myriad comments in agreement, you seem to be either behind on research or research itself is behind. I hope you’re able to expand your thinking.

They explicitly aren't dismissing the pain, controlling the pain, being stoic about the pain, or arguing that you should ignore or suffer through pain. Read it again.
Your idea that RSI is in your head has the same issue: "It doesn't work that way." SOME pain is in the mind. Some pain in the body can be mitigated with mental techniques. Some.
> all pain is just based on expectation
This statement is wildly false.
Now, I studied pain control, and when I fell into a hole and was injured in Bali, I was able to function and even continue to speak Indonesian until I got to medical help and could pass out, simply with breath control. I almost never take painkillers. The technical of detaching from pain has significant value, and I have taught it to others.
But some things are wildly painful and can't be dismissed that way...
You know, I'm not even going to type about some miserable things I have briefly experienced, and some horrible things I saw happen to other people, other stoic people even, or about objectively provable imaging (X-rays, etc) of damage caused to people by RSI.
Life is too short for such downers. We both know they exist.
Your ideas do not agree with the consensus of medicine, or the experience of humans. You should re-examine your beliefs.
I do hope you never get first-hand experience of how very wrong you are.
