I went to the doctor around 4-5 months ago due to swelling in my lower right abdomen. It feels like something is in there and I told her that. She felt around and said that she couldn't feel any lumps/masses. She never ordered tests, so I just figured that it would eventually go away. The swelling doesn't seem to be there at times, like in the morning when I first get up. Lately,I can see feel and its evident that I have swelling(the doc didn't think so), and I've been getting small sharp pains in the same area. Could this be IBS? It's always in the same spot and doesn't move. This is driving me crazy! Could gas just be in one spot and not move and cause swelling?
