I have a lump under my right breast seemingly on top of my rib really close to my sternum, it caused problems before such as pain when I slept on my chest but now that Ive been wearing my bra less its been easy to ignore. I went to my doctor and he said I have inflamed cartilage from overexertion at the gym. He may be right but why would I only have a small lump of swollen cartilage in one particular location? I took an X-ray that day as well but he didnt talk about it and just decided to prescribe an anti inflammatory drug. Do you have any ideas of what might be going on with me?
Hello! Thank you for the query. Such lump can be inflamed cartilage of the rib. Please note that ribs are connected with the sternum with cartilages what allows chest to move. In case of any injury, over strain, an inflammatory process can appear. It is also possible that you have broken this particular rib. Any fracture repair causes a kind of lump where the bone is rebuilded and repaired. X-ray can give an answer. Also, ultrasound of this area can reveal an inflammation. Hope this will help. Regards.
