White itchy bumps on neck

Hey girls! I’ve never had this before lol but a small part of the bottom of my neck started itching yesterday. Of course I itched it lol now I have these small white bumps which are red now because I itched. Anyone know what this is or how to stop it itching? I have no idea what or how I even got it.
