I have a handful of diseases which sometimes produce similar symptoms, so I can't always tell and my doctors probably wouldn't try. But I know that my worst symptom now is very bad leg and hip neuropathy. I am trying everything I know, but have not got it under control. I do a lot of praying lately, and I am stymied. I have seen the pcp recently, as you suggest, Sally, and she doesn't have very good answers, but is sending for various tests. Her changing my diuretic and potassium intake just produced a potassium deficit, which I've had before. I am an experiment in progress so I don't blame the pcp. If I blame doctors it is the meatheads who didn't dx me when I was younger.
