If you continue with this pain I would go to the ER. They can take an xray/scan to see if you have a blockage. I experienced this and because my doctor was in NY I had my husband drive me all the way there that night as the ER scared me about the need for possible surgery if the blockage worsened. After the evening it did pass on it's own. I happened to eat some bran cereal that day and had a lot and must have stopped things up a bit. I did not have any infection at the ostomy site though so I am not sure if you can be dealing with an infection or not. I just had a lot of abdominal cramping and pain and it seemed to come in waves and a heating pad did nothing for my pain or discomfort.
