I'm 16 years old. For 4 years now I have had stomach problems. I wake up in the morning from nausea, not long after i get diarrhea, my whole pelvic area feels like its in knots, along with my abdomen. Most of the time i will retch for about 20 minutes throwing up white foam or stomach bile. Up until the middle of the day i feel really week, have no appetite, and cant eat without getting nauseous. Throughout the day i get horrible pains in my upper right quadrant. Underneath my right rib cage. my joints are always sore, and my right side of my back and shoulder, (parallel to my gallbladder), gets really sore with a hot stinging sensation. I have been to a GI doctor and had 2 upper endoscopy's, a flex sig, and a colon endoscopy. Nothing came back besides ulcers. I had a hyda scan done, and my gallbladder is functioning correctly. I also had an xray to check for malrotation, which was negative. I have been checked for celiac disease and crohns but nothing showed. I recently had a stool sample and it came back normal. I also have a low grade fever every day. Can someone please give me some direction as to what this could be?
