Hello, I have a lump on my forehead that has grown over time. When I first noticed it, it was small and not that noticeable. However, recently I have noticed it has grown bigger. People are more noticeable of it and constantly ask what happened to my forehead. I don t have any pain, it feels like bone, and does not move. It is below my hairline on the left side of my forehead. Do you know what this could be and what the causes are?
