Don't pop them, apply bacitracin or neosporin ointment (no prescription needed), and show them to a doctor if they haven't gone away in 2-3 weeks. They're probably blocked pores or ingrown hairs. The pins and needles sensation comes most probably from a combination of inflammation and worry.
Take care.

Ive applied some hydrocortisone to it and it hasnt helped much yet. It sort of burns a little sometimes- like a chapped lip, but isnt really painful or itchy at all.
I do shave with a blade at least every other day...maybe that has anything to do with it, or should I go get tested?
