I got one on my forearm because of some sort of allergy. I'm not even sure if it's an allergy but I think it's some kind of skin irritation. Also got one on my left knee but it's hardly visible now and another one on my right foot because of my shoes hahaha I have other scars but they aren't visible anymore. Idk
Some nigga tried to kill me when I was still a baby but my mother's love saved from death so now I got this lightning-shaped scar in my forehead. True story.
