My husband complained of severe abdominal pain . CT showed thickening of the ileum . Negative for diarrhea ,fever, nausea. Appendicitis , cholecystitis was ruled out. About 6 months ago, he had the same symptom, was treated with antibiotics. After 2 weeks, the thickening disappeared. A few days ago, it recurred. He is currently on antibiotics again.Thank you.
