I lacerated my head and got 5 staples near my hairline. The back of my head is numb and itches.?

I had a vasovagal episode ( fainted ) and split my head needing 5 staples near my hairline. The actual lacerated area was not really that painful although having the staples put in with no numbing was fun. Having them come out was worst but it's over with. My question is that the back right side of my head is and has been since the injury, numb and itchy. Sometimes I have to pull my hair to relieve this. I'm wondering if I should be concerned or if this is normal, possibly I did nerve damage and it will take time to heal? If it were the area that I split open it would make more sense to me.
