Hi wpr7573: Yes, I used to have severe cramping just like you described. The first time it happened, I did want to call 911, but couldn't even get off the floor. It was so bad, I couldn't breath or move, just be in agony. Then, I passed out fromt the pain. Once I came to, the cramps were gone, and I immediately went #2. I am IBS-C so anytime I go #2 is a welcome.Those cramps came on about once every 6 months for a couple of years, then more often until they came every few weeks. I never called 911 as I figured out that after a couple of hours, I'd be fine, but the fact we even have to go through that is awful.I finally got help from a doctor (after many sluffed me off). He gave me an anti spasm medicine. I haven't had severe cramping for about 8 years now (after 25 years of cramping).
