i have a hard lump on my first rib right where it attaches to my sternum. It isn;t painful, but sometimes it hurts, sort of a aching feeling. It keeps getting bigger. I had it checked out and and a doctor said it was my skuliosis causing my rib to be higher than the other. But im 21 and i never had that lump there before .
Thanks for your question on Chat Doctor. I can understand your concern. I don't think it is Scoliosis. Scoliosis is related to spine, not sternum. Scoliosis is sideways protrusion of spine. So I don't think your lump near sternum is due to Scoliosis. In my opinion, you are mostly having Costco Chat Doctor.  It is inflammation of costal cartilage, and it can cause swelling. So follow these steps for better symptomatic relief in Costco
