8-| Hello. I have an 8yr old son & his father discovered a sore in the back of his head during a weekend visit. Its quite large, quarter sized, scab & has puss under the scab. I was getting him dressed for school & I saw 3 or 4 more. They were smaller & not as bad as the first. Kind of hidden by his hair. The first one you can see plain as day. He says they hurt when I touch them & they itch bcause he has been scratching them. WHAT'S WRONG WITH MY BOY???
He may have a skin bug of some kind, such as fleas, ticks, or other bugs. Take him to the dermatologist. They would know if he does have a bug infection and what to do.
