About 1 1/2 mos ago I had severe heartburn, abdominal pain, back pain. The heartburn traveled from my chest to my navel to my right side. Had all tests for female heart attack including catheterization and all came back negative. Last week I had another episode, not quite as bad, but needed to take another nexium at night and tums during the day. I have reflux disease and IBS. Had colonoscopy and endoscopy 2 years ago and tests in 2012 (MRI, etc) since I have constant abdominal issues. I am taking carafate before meals. I am usually taking amitryptaline for intestinal spasms but stopping for now. What could possibly be wrong, and how do I get this to calm down? Help!
