question: Since last Friday, everytime I eat a full meal, within 20 minutes after finishing I get a throbbing pain through my lower abdomen, radiating around to both of my kidneys. The pain in my back feels like kidney stones (I have had first hand experience with those) and the abdomen pain feels like gall bladder pain (which can t be because I don t have a gall bladder anymore.) The only thing that makes the pain go away is my heating pad. Any ideas as to what might be causing these episodes? Signed Ruth Peyton YYYY@YYYY
