I have been having diarrhea lots after eating now it is most of the time, as well I get very dizzy when I get up or bend over,very tired, I have lost over 20 lbs,and my appetite is poor especially bad with meat I can't eat any meat without feeling very nauseated and sore stomach. I get severe cramps in my stomach then bad diarrhea comes,I wake up feeling nauseated & my mid lower back and hips really hurt and now the shin bone of my left leg and my right forearm have been very painful. I have had blood tests,chest xray, and ultrasound all showing nothing but I am just miserable feeling like this.
