I had a colonoscopy on June 18th and was told some polyps were removed but everything else was fine. Imagine my surprise to have to be admitted to the hospital on July 17th with severe lower right abdominal pain. "Diverticulitis". After 3 days of IV antibiotics I still feel really weak and have pain. My question is, how long does this take to develop and how long till it goes away? I don't trust the doctor who did the colonoscopy anymore because of this and I don't want to contact him about this until I have some answers.
