I started having some sharp abdominal pain yesterday. It started in the afternoon, a while after eating lunch (sandwiches, but the meat may have been older than I thought). It wasn t severe pain and it went away after an hour or two (after a bowel movement). I ate supper last night and a short time later, the pain came back, but it was very severe and I was doubled over for the rest of the evening. I had a couple of bowel movements, but they did not seem to help the pain. When I woke up this morning, the pain was almost completely gone, but then I had a few sips of coffee and it came right back, although not as severe as last night. I thought maybe it was food poisoning from the sandwich meat yesterday, but it has gone away and then comes back every time I eat or drink.
