I did it because I used to be a boxer and had my nose broken a few times.
I had reconstructive nose surgery from this Dr. in January of 2006. He took cartilage from my ear and put it on the tip of my nose for better support. When the bandages came off and the swelling went down I noticed a bump that goes across the tip of my nose where he put the cartilage. He said it was from the swelling and would eventually disappear. More than four years later it is still there. Twice he made some minor tweeks to correct this with no success. I have had many people ask me "did you get a bug bite on your nose?"
I am a performer in the entertainment industry & I have lost a considerable amount of film and print work due to this issue.
