I’ve gotten those from time to time. I believe it is just an ingrown hair. This sounds painful but it isn’t bad at all compared to the iritation of the festering ingrown hair.
Good tweezers, rubbing alcohol, and a straight needle are needed (nowdays I don’t need the needle but it is a little easier with it).
First, clean the sore, tweezers, and needle thouroughly with the rubbing alcohol. Then lightly pick into the highest point of the bump.
Do NOT go to fast or deep because you will hit nerves. By steadily picking at the bump you will get down to the hair folicle with little pain. There might be a good deal of blood coming out so be prepared. Slowly pick/pry the ingrown hair out of the skin (the hair will still be attached at the base). Finally pluck the hair with the tweezers and clean up with the alcohol.
Note: A triple antibiotic ointment will accelerate the healing process. With this ointment it usually heals in 3-4 days.
