It happens right after I eat a large meal, and I feel nauseous, then I vomit. Then I have this terrible burning
pain in the
lower left that radiates to my
back and upward. I will then have the urge to have a bowel movement. While I go, the pains get worse, but when I am done, they go away for a few minutes then come back just as painful. When I go, its like diarrhea, only its got little pieces of stool in it as well as water. This goes on for about 8 hours.
