Stupid surgery on my chin, the rest is self explanatory

I'll explain a bit
The green on my forehead/nose bridge is when my older brother accidentally dropped me and I hit the beds corner. The thighs is when I got allergic to a vaccine, the back of my head is when I fell off a hammock

The back of my legs is when I lived in my old house, the door would something scratch off skin. Me and my brother has this

A girl pushed me in ukg and I bleeding everywhere
I still have the scar

On my chin
