Wow, I can connect with you on so many points--but I've gotten not a single diagnosis. & I've not had any surgery. My pain started after I was put on statins. But burning, tingling, numbness? Yes. Out of control? Yes.
I really perked up when you said you went off meds & tho it was very hard it got better. I think that's a big clue.
I'm not sure which of these forums would include your concerns--probably more than one. If no one else stops by to direct you, I'll look thru the possibilities & come back later with some suggestions.
In the meantime, stay cool. Literally, if nothing else. Are you taking something now for depression? How bad is the RC tear?
