This is my first post and I'm hoping to have some relief from the severe stress and anxiety I've been experiencing this weekend. I found a hard lump on my lower left rib cage on the side of my abdomen. I'm freaking out and of course have googled everything possible and convinced myself that it is some sort of malignant tumor. Has anyone experienced this before? I'm making an appointment with my doctor tomorrow, but in the interim, cannot eat, sleep or do anything other than obsess about this. My Dad's girlfriend (who is an OR nurse) felt it yesterday and said that it was probably a lipoma. Everything that I've read on the internet though states that lipoma's are soft and moveable, and this feels hard, almost like bone. I'm freaking out. I'd appreciate any insight anyone may have on this.
