Hi. I had left hemicolectomy about 15 years ago due to repeated diverticulitis. Recovery went well and no further bouts of diverticulitis until... A couple of weeks ago I began having pain in my left side just below my waist. There were no other symptoms so I gave it a few days to, hopefully, return to normal. I was concerned that I'd have to see a doctor, get a CT and go on antibiotics, URG. When symptoms did not return to normal I put myself on a low residue diet. Two to three days later things were back to normal. What a relief. Hope you get the answers you need without any bad problems.
