What could be wrong?

Jackie
I usually get cramps 2 times a year and they are te worst! I get hot flashes, i cannot walk, i vomit, i feel my insides are falling out, i get a acute pain that lasts for about one minute then goes away for 3 seconds and come back. I feel so hot that i have taken my clothes off while in the car. I can't stay still i move and move and turn around in pain. I take a pain killer and after a while i fall asleep and when i wake up its gone.
​Anybody has an idea of what its wrong??Thank you
