I got surgery done in May 2016 due to a broken nose from a car accident. After a month or so I noticed a bump forming on the bridge. At first I thought It was a pimple but I soon realized It was not. When I stretch my face the bump does not move, and is white. My surgeon said it is probably calcification, and to get a minor revision surgery, but I am worried It will come back. What are the chances this issue could happen again?
