It could just be his skin. Have you ever gotten those type of bumps on your upper arm? My husband and I both get that and it gets worse when the weather gets warmer. My daughter got doubley blessed with it. Her pediatrician actually brought it to our attention. She called it "chicken skin." If that is what it is, then there isn't much you can do about it. Just don't pick or scratch at it. Easier said than done.
She gets them on her cheeks, her arms, and her legs. Her baby sister has true baby skin.
Get it checked out regardless.
