Hi, Its been now over 5months and everytime i go to gym and do a jog or walk on treadmill i start having urine burning. I have been through different uti tests and nothing comes up. In addition i feel inflamation and uncomfortable in rectum area and sitting for over 2hrs makes my condition worse. CT is clear and shows nothing.i have bit of constipation with external hemerhoids as well. But iam staying on top of them by controlling diet. Why is it the problem gets worse when i sweat and do any exercise related to lower abdomen. Please advise.
