Hello. I'm Dr ChipThanks for your question and I'm reviewing it.I'll be back in a moment with and answer or a request for more information
This is either folliculitis--infection around a hair shaft--or a small infected benign cyst
For now you can apply an over the counter antibacterial ointment like Neosporin twice a day for a week
That should clear it up, but, if not, you'd need a course of oral antibiotics from your doctor
Please let me know if you need any more information
