I have a lump on the left side of my upper stomach area to my side by the bottom of my rib cage. its extremely uncomfortable,it almost feels like its pulling. I feel like its pressuring inside me. Its making my shoulder even hurt. I got ultra sound results today and there was nothing found on my organs, no tumors or anything, WHAT IS THIS LUMP?? Its uncomfortable to the point of not wanting to do anything, and is making me so upset and scared I feel like throwing up. Has anyone had this?? I am really scared. I have another appointment next week. My doctor mentioned perhaps a hernia but I am skeptical. HELP!
