When I woke up this morning I had a pain in my lower left abdomen. I was constipated too so I figured it had something to do with that. I got through the day and the pain persisted but wasn't too bad. But as the evening came it got worse. It went to my back and shot down my left leg to my knee. It's 4:30 AM now and has just gotten worse. I woke up to go to the bathroom and could hardly move. Now the pain is keeping me awake. Waiting til 8:30 when I can call my doctor. What is this?
