Hi, I have a lump about the size of a golf ball at the base center of my rib cage in front of my chest. It doesn t really seem to be painful, just uncomfortable mainly knowing it s there. I can really feel it when I m bloated but can still find it regardless. I noticed it a few weeks ago but wasn t sure if it s normal or if I was really feeling it or not. I had someone else feel and they felt it also. Should I be concerned and go to the doctors?
