Hello, I am 15 years old and I was in a small bike accident around 8 years ago and ended up having to get a few (11, I think?) stitches on my chin, which were removed a few weeks later. Everything was fine until this past week, when I started seeing that the scar was getting inflated and began hurting as well. I initially thought it was just a pimple so I didn't worry about it, but now, after some research, I see it's starting to look like a keloid scar. None of my relatives have any history of keloid scarring so I do find this quite odd since I read that one is usually genetically predisposed. Now, isn't it quite odd that this happen 8 whole years after the actual injury? What are the other possibilities? I'm going to see a dermatologist soon, but is there any temporary treatment in the meantime to prevent continued growth?
I'm a male, by the way.
