i'm 15 years old and on the top of my head (where the hair swirls in the back) there are a few scabs that DONT go away. every once in a while the area just below the swirl (sorry if i dont know what its called) will start to itch and i will unknowingly scratch it to find that it bleeds. i am a sophomore in HS and i can remember this happening all the way from 5th grade. i've been told that when i was just a baby the doctors had to put me in a straight jacket and pull a growth of some sort off the area described. How can i treat/stop this?
