I was wondering if anyone else has constant muscle weakness. my muscles in my legs and arms constantly feel weak and they ache. I asked my rhuemy about it, because I wasnt sure if it was side effects from cymbalta or if it was the fibro. he said it was the fibro. but I don't seem to get any relief, other than getting in my hot tub. I walk 1-2 miles a day and they still ache. any one else have this problem?
