I recently went to the doctor because of some pain I was having on the right half of my rib
cage and my back. I was diagnosed with costochondritis (inflammation of the cartilage in the
rib cage, caused by sever coughing, getting hit, even laughing) and I was put on a steroid to reduce the swelling. One evening I was massaging my aching side when I came across a lump on one of my ribs...I had never noticed it before.
