OK maybe it is nothing but whenever I pick at my scabs (disgusting habit i know) and they start bleeding, the right side of my head feels weird...almost tingly. I don't bleed much but I just want to know if I should be worried. If it helps, I am 14 years old, and it has been going on for a little over a week. I used a bandage that I am apparently allergic to. I figured that out when it left a mark that caused more scabs because i scratched at it (it itched).
