I am 37 years old with 2 children. I have been experiencing lower pelvic pain that is not cramping but dull burning amp; aching. It worstens at night and I feel awful by morning but as I get up and walk around it subsides some. The pain also Can be in my lower rear when sitting for prolonged time. I've had a normal CT scan and ultrasound. Blood amp; urine work clear as well. I have been on flagyl for infections but that did not help. So the diagnosis is possible ibs but in general my stool habits are normal. I've had a normal colonoscopy as well. My GI doc has put me on Bentyl amp; Zantac and restricted diet but they do not relieve the night pain. Can ibs worsten at night? Any suggestions for relief would be a big help!
