So When I Was Little An Accident Happened And A

So when I was little an accident happened and a glass lamp fell, shattered on my leg, around a few inches above the knee and I received a scar. It has been a few years since the incident, maybe 2-5 years and now there is white patch of white stuff on top of the scar. No glass was in the wound and the white stuff was very wrinkly but only when you squished it. It was also soft,smooth and slightly above my skin
