I broke my left clavicle in a mountain biking accident about 3 years ago?

I broke my left clavicle in a mountain biking accident about 3 years ago. The break had an overlap and they decided st the hospital to not do surgery and let it heal as it was. My problems now are there is a large lump sticking out from the position of the overlap that is aesthetically very unpleasant and also causes pain/irritation if I’m carry something over that area like a backpack. I wanted to know if there was a surgery option to cut down or smooth off this overlap bone that is sticking out under the skin. I’m very self conscious about this, and it effects my confidence and I’m always feeling around that area every day. Thanks.
