I hit my head very hard when I was around 5 years old and got those two bumps on my forehead. I am currently 15 now and they haven't gone away. The doctors told me they are calcified bones and I should worry about them. They don't hurt or anything but it makes me look very embarrassing. I heard incision above my hairline could be done and shave them down, is that true? Also I'm concern about the cost, few hundred? few thousand dollars?
