Have you considered Lyme disease? I've looked at your long list of symptoms and I have/had many of them. I was diagnosed with Lyme disease in Jan. 2008. I even had a sort of "dent" in my right thigh a few years ago, it was pretty bizarre, no one could tell me what was causing it; it's back to normal now. I also had episodes of taste and odor hallucinations... My symptoms list is very very long.
If you want, you can write to me and I'll help you find a Lyme specialist in your area. [email protected]
