Doctor suspects IBS after most everything else checked OK. I see by a lot of posts that most here have C or D along with the abdominal pain. My abdominal area hurts and I will burp for hours but no C or D at all. I am on previcid for acid, but if I have IBS,what good is previcid? Again I guess I had too big a lunch but a very lite dinner. This stuff is so miserable. I wish it were a gallbladder problem so it could be removed. In about two hours I will feel Ok again, its just lasting till then.Jerry
