There are other things besides MS which might make you ache all over. I was aching all over worse than before when I finally was dx'd with Porphyria. I lived in San Diego too, and it was a high "ache" belt for me, with all the mold, although I miss it so much here in the high desert, where I ache less. I don't know why you ache but I believe it is not just "old age". I don't know of a good doctor still practicing in San Diego who could think about other possibilities for you. I found Scripps to be my best place, but they did not diagnose my Porphyria; no one in California did. I understand your confusion. We moved away from San Diego and the whole west coast because of me having worse symptoms there. Possibly a starting place for you would be to go to a Hematologist at Scripps Medical Center--that would be just playing roulette, to hope for a dx there, but I found Scripps to be among the best there, as I said. New Mexico does not have total medical care, but it is at least "dryer".
