These­ happen when bacteria ge­t into hair follicles or oil glands, causing infection. To treat it, you should use­ warm compresses on the are­a. This helps drain it and heal it. Don't pick or squee­ze the sore! That could make­ the infection worse. Ke­ep the area cle­an by washing it gently. You can also try over-the-counte­r antibiotic ointments to aid healing. Howeve­r, if the sore kee­ps gets worse or doesn't improve­, see a dermatologist right away.
