Good afernoon doctor. I ve had a stomach problem for a while. the area just above my belly button swells each time i eat, and i get a lot of gas and bloated feeling. I ve been to the doctor more than 3 times, and each time, i get medication that just works while am taking it. As soon as the medicine finishes, the gassy feeling comes back. I have had an ultrasound done, as well as stool and urine tests..all came back ok. Can you tell me what this could be?
