Ray, that is exactly my question. My pain doc is trying to get me into a neurologist and hopefully he/she will have some insight. At my last appointment (this week) I mentioned that I wondered if it was possible that I was developing M.S., and after fielding my intake (it is 3 pages every appointment) he and his P.A. also threw out the possibility of Parkinson's. My symptoms are different from yours, but other issues are always "out there", it seems. I think our docs generally do the best they can, given the complexity of the human body and the millions of combinations of symptoms that they are presented with. But it sure is frustrating anyway, not knowing.
Hope you have a restful and safe weekend with the coming heat! If I remember correctly, you are thinking about combining your household with that of your longtime partner. My thought is, one's health and ability to make physical changes is usually better now than later. Best of wishes and blessings to both of you!
