Fainted and had a seizure on July 22, bump is gone but when I itch my head it still hurts where the bump is, is this normal it hurts so bad?

Pain on the surface. Yes this spot could be sore for a while, but it should not be permanent. Especially when you scratch there. It remains in a hypersensitive state. This should resolve. Have you had any other seizures? Hope you are otherwise doing well.
