I ve been told that I have a gallstone, which was picked up on the CT. Right now I think I m having a gallstone or rather gallbladder attack . How long should I wait before I go to the emergency room ? I had some cheese and some dried salami, and typically, I don t eat those fatty foods. I m in pain at a level of a 6 to 7. But, I don t have nausea or a fever. This started about six hours ago with pain to my epigastric area, now it s migrated to under my right ribs . Shall I wait it out? It seems to be subsiding a little bit after aspirin and Rolaids.
