I have a boo boo in my arm it has red spots on it and it turns yellowish, what is this?
Is this just okay or not? my arm has a boo boo and a little deep scratch on it with red spots and it turns a bit yellowish is this fine? I don't go to a doctor, I don't even go to my parents, and I don't have any idea what is this?

a person scratched my arms deep it bleeds and with a boo boo after about 2 days it turns yellowish and my hair in my arms for where is the boo boo is has red spots on it...

Actually this sounds like a contusion with abrasion.
(A bruise and torn skin).
The yellowish part is the bruise in its waning cycle, as its healing and going away. This will heal on its own.
Trust me your arm isn't going to fall off!
Show your parents, they should see these things, silly.
