I am a 43 year old female with a medical history of kidney stones at least one a year and gastric bypass 10 years ago with no complications. I went to local ER 8 months ago with abdominal pain, sure that it was another stone I was surprised when they informed me that they were admitting me because the CT showed thickening of the ileum. I was there for 3 days treated with cipro, flagyl and pain medication, and put on a liquid diet. Released on a BRAT diet and same medication to FUp with GI. GI did colonoscopy and said not crohns, said it was probably IBS and I should just watch what I eat. I have been suffering with the same pain for over 2 weeks now, been back on the brat nothing is helping. I don't want to f/up with GI to be told IBS just watch what you eat. What could be wrong?
