two days ago i woke up at 8 a.m. to go to a class.. as soon as i sat down in the class i got SEVERE cramps in my lower abdomen... I could barely sit through the class and I felt like i was going to die or pass out from the pain. Yesterday I slept in until 1 p.m. and was fine. Today I had the early class again and right as soon as I woke up around 8:30 a.m. I got the same severe sudden pains. The only slight relief is to lay down.. so I couldnt make it to class. Does anyone know how what this could be?

I had a colonoscopy done a week ago, could that have anything to do with these cramps?

Yes they could, I too have severe stomach cramps to where I actually do pass out. I was diagnosed with vasovagal syncope, which means fainting from pain sent to the vagus nerve. It's nothing serious but can be scary. Everytime I've pasted out it's been from abdominal cramps and I got a seizure 2 days ago and was admitted into the hospital from the abdominal cramps. That won't happen to you though, you could have syncope or it just could be from the biopsys they took.
