A couple of nights ago I had horrible stomach pain that would come and go lasting for about 3-4 hours. It got so bad I thought I would have to go to the emergency room, but I have no insurance. The next morning it was lessened, but I kept having very watery bowel movements. I have been having random stomach cramps all day for the last couple of days. I have not eaten much because of the cramps I get when I eat. What could this be? Should I see a doctor? I am in very good health otherwise and I don't eat any meat.
