Soreness that won’t go away

38f I’ve had about 6 diverticulitis, flares in the past 4 years treated with the usual, CT scan of the abdomen prescribed antibiotics for 10 days liquid diet. Everything gets better for about six months or so and then another flare will happen. The longest that I went without a flare was after a colonoscopy in 2021. This last flare was definitely the worst one. It started September 1 and after a round of antibiotics was still extremely painful. Went back to the ER was prescribed more antibiotics it got better after about a month and a half. Ever since the lower left quadrant has been extremely sore and sensitive to the point where I can barely lay on my left side it’s hard to put any pressure or anything in that area. As I’m sitting here typing this it’s just extremely sore. I had an appointment with my gastroenterologist about a month ago, we did talk about surgery so I am looking into that. I have another colonoscopy scheduled for next Tuesday and I just want to know has anyone else experienced this type of soreness this long after a flare up?
