I have been having upper right abdominal pain under my ribs for about 6 months now.. Since then I have gone to the doctor and had blood tests, x-rays, and an ultrasound on my gallbladder, liver, and kidneys. Everything so far has come back normal. Could someone tell me if this possibly is result of muscle strain? I do carry heavy objects everyday. Also, there is a weird popping feeling in that area when I breathe in sometimes.. or if I push on the ribs in that area. Since the ultrasound came back normal, can I be pretty sure that its not my liver, gallbladder, or kidneys causing the pain? Im not sure if this is related.. but my stool has been kinda yellowish and soft lately. Please give me any ideas you have on what this could possibly be.. Because it seems the doctor has no idea. Thanks!
