Male and have a bone in my chest that sticks out a little. sometimes i get chest pain from it. can this cause damage?

Location and duratio: Where is it located at ? How long was it there ? Are we referring to the rib bones or the one in the center (sternum)? Is there additional growth or is the whole bone is puckering ? I am not clear with the description and difficult to make remark . However , some harmless changes are common and should not be of any concern . I suggest your doc have a look and will settle the issue for you.
