Every couple of years, I get renewed energy to try the search again. It lasts for a year or two before I run out of steam, give up, and decide to live with it, because I'm easily 6 figures into trying to be able to walk without pain and not be laid out with a headache every month.
100% of doctors started with telling me the problem was my weight. I lost 50 lbs and all my symptoms got worse, so they pivoted to telling me it's psychogenic. All of them. But I've been through all the recommended types of psych treatment too, and a few experimental ones besides.
In point of fact, I cannot convince anybody who might know to care enough to find out, and it seems unlikely I ever will. There doesn't seem to be any good reason I should be stuck with these pains, but there are only so many times I'm willing to try the same things, expecting different results, because this doctor thinks all the other ones must have been too stupid to rule out the obvious causes.
