Pimple sized bump on scalp that’s not a pimple?

Anyone know what this might be or if I need to worry about it? I’ve got 2 tiny bumps on my scalp that I’ve noticed just from when my head randomly itches I can feel them. They’re tiny, the size of a pimple but they’re not red, don’t hurt, and they seem to be under my skin. They’re not bothering me at all they’re just there. Been there a few weeks maybe? Not sure. I didn’t think anything of it but just started wondering if that’s anything I need to worry about
