So, i am not on my period, but for the last 36 hours I have been experiencing intense menstral-like cramps. There is shooting pain in my rectum when i sit down; there is intense pain when I have a bowel movement. It feels like extreme constipation, but my bowel movements are regular. It is uncomfortable to urinate, and I have to force or push my urine out. There is no blood, not nausea, no vomiting. Just Pain! The pain comes in waves, but especially when i initially move or sit down.
