Hi, about a year ago I accidentally hit my head, the middle of my forehead, on a metal bar from a workout set. After compressing it with ice and bandages the blood stopped and swelling went down some. Since then I ve used Mederma and Vitamin A (I think) for the scarring and bump itself. I was wondering why is it that I still see the scar, and why i still feel a bump. Also, if i ever hit the bump by accident, it will swell up/grow, only to go back to the previous size few hours later. Is there anything i can do to prevent this bump, scar, and or get rid of it?
