Rubixqueen, I'm having the same issue. I went and had a CT scan last week. They couldn't find anything. I'm having a MRI tomorrow morning. I think I'm more worried they are not going to find anything and I'll be back to not knowing why I hurt so bad. I've been running low grade fevers in the afternoon and have lost all energy. Those two things are the reasons I'm thinking something is going on. My doctor doesn't seem to be too concerned though. It wasn't until I said something isn't right that he ordered the MRI.
Oh by the way, the stuff doesn't taste too bad. I did take off work and I'm glad I did. It has a mild laxative in it. Crohnie's don't usually need laxatives. I had an accident on the walk back to the car.
