Hi im a 17 year old and recently noticed that I have a hard protruding area coming off of my sternum into my right breast that isn't there on my left one. I have pretty bad health anxiety and this is freaking me out. I have seen other posts saying this is most likely a protruding bone and not anything to worry about. I do have a lot of more prominent bones on my right side including a rib that seems to stick out but I am still worried about it.
