@jlharsh My gi dr ordered an ultra sound and ct scan looking for a hernia. That was negative. He thought it might be scar tissue but removing scar tissue is tricky and can cause more scar tissue. The pain started about 8 years ago, before I was diagnosed with diverticulitis. It lasted less than a minute. It was very painful and out of the blue and very weird. A twisting pain. Felt like something was caught inside. The area was tender for several hours. It didn't happen again for probably 6 months. Very random. I mentioned it to my internist and she just shook her head. It wasn't happening very often and the pain was over with quickly and wasn't effecting my life. In 2020 I had a colovesical fistula. I had absolutely no symptoms before. It caused a severe bladder infection and that was how it was discovered. I had blood in my urine The colonoscopy I had 2 years previous to this showed diverticulosis. The sigmoid was very diseased to the point of creating the fistula to my bladder. As far as I was aware I never had a fever, and definitely no nausea or other common symptoms of diverticulitis. I have had that grabbing pain maybe 7 or 8 times. in the last 2 years Two days ago I was sitting on the screened porch floor trimming my dog and that pain happened again. I will say I was in an awkward position with my legs akimbo and I was bent over. This time it happened twice in a row in a few minute span and that area of my lower left abdomen is still tender to the touch and I have a mild discomfort. I exercise 3 times a week in a class and it never triggers this pain. My previous abdominal surgeries were for 2 ectopic pregnancies, one of which ruptured, 2 c-sections and open surgery to remove my gall bladder.
