I was diagnosed with costochondritis which is an inflammation of the rib cartilage which causes me a lot of pain in both my chest and breast , the hospital said it should clear up on its own . I had blood tests done to check if everything else was normal I'm still waiting for the results but I was feeling my ribs to see if they stil hurt as much and I'm not sure but I think I might have felt a bump or bump on one of my ribs on the left side below my breast I'm not completely sure tho but I'm slightly worried can anyone help?
