What does an episode feel like and where is pain? I do have diverticulosis. I get this lower left front pain. I tested positive for UTI w blood ( frequent pee urges and burning pee or cant pee. Took antiobiotic. Urine test now clear with blood. Lower front left still was painful. Given2nd antiobiotic last dosage last night. I still have lower left front pain. Feels like sitting on something painful. It occurred to me yesterday I might be having diverticulitis attack. In reading there is close association between UTI and diverticulitis attack. Went to clear liquids yesterday. No other symptoms….just painful left front feeling like sitting on something painful or pain is radiating from bladder. Now I know the colon can be resting up against my bladder. So what does your pain feel like and where is your pain. I am using my hyoscyamine, baclofen, and Tylenol to treat.
