From last 45 days I am suffering from abdominal pain, discomfort , bloating , gassiness , fullness all the time, heaviness in back with constipation. Some times I feel a knot or tie shaped structure bellow lungs or just above the stomach. It alters time to time in size. All the investigations like endoscopy, enteroscopy , colonoscopy , ultrasounds, blood tests & x-rays are normal or negative except ct scan of upper abdomen in which jejunal thickening has been found. I hv visited physicians, gastroenterologists & Gastro surgeon. They have given me razo tab, domstal, dufalac, rifaximine tab , eldicet tab , mesacol tab one by one. But still I am waiting for a treatment for my problems. According to my symptoms I feel it is irritable bowl syndrome but no doctor has pin pointed same. Kindly suggest me ???????????
