I had my JPouch surgery with loop iliestomy 2 weeks ago. The bad nausea began 4 days ago, I feel real bad, I also have discharge from my butt - rectum was removed. I'm suffering from pain but the nauseas are so bad I don't want to take pain killers, I'm drinking fluids to prevent issues. Can someone give an idea how long is this to last, should I go to the er? Please advice
