Hi, I've never done this before but am at my wits end. Starting back in February I've had issues since being on antibiotics for an ear infection. Since then I've had pain pretty much every day mostly on right side just under ribs and on ribs and on side of ribs and also sometimes on left ribs. At first I pooped a lot and had diarrhea. I was tested for colitis and celiac which were negative. No blood in stool. Had an endoscopy which said I have gastritis. I do have acid reflux which I take nexium. I was also given antispasmodica which make me constipated. These days I still have pain and go from constipated to diarrhea. I just can't believe this constant pain could be ibs and my anxiety makes me think cancer. Oh and I'm a 35 year old female. Any thoughts? Doctor doesn't think any reason for a colonoscopy. Today I had a hida scan to rule out gallbladder issues, previously I had an abdominal scan which showed nothing. I'm so worried!
