56 male While urinating today, upon finishing, I had a pounding headache, that was unusually painful. My bladder is becoming troublesome, but know prostate is not the problem. For last few weeks, my entire digestive system has not been normal. However, I have not had big appetite either. No diarrhea, just long periods between deposits, like it s taking longer than normal to digest? Wondering if maybe this could be a signal of diabetes?
