I had a CT Scan recently that showed possibly a polyp, tumor, structure, thickening inside wall that might be inflamed or an infection. Both infection and inflammation were ruled out by blood tests. All blood tests were normal limits that were run. My gastro dr says we can diagnose diverticulosis for awhile and see if I have another episode. I have no pain now and bowel movements are normal. No bloody stools. I am 82 years old and would like to have a second opinion . I have problem with anesthesia causing my blood pressure to spike and trouble stabilizing it after . Therefore I am not wanting a colonoscopy at this time. Your thoughts please.
