For about the last three years i have not had a normal bowel movement it goes from pencil line movement to a extreme liquid movement. all this is started with a bloating feeling in my upper stomach as if my food is not digesting at all as if it sits in my stomach. this is followed up by Sulfur burps (eggy burps). after about 12 hours comes the extreme pain and cramping and then the diarrhea. and the worse flatulence i have ever heard come out of a human. lately about the last month it has been every other day i have been on prevacid and nausea meds but nothing works all food seems to set it off. i dont know what is going on and it bothers me alot.
