It seems you are suffering from Folliculitis
. You can take any good painkiller like paracetamol
for two time a day, you can apply clindamycin
gel and take cefadroxil or ciprofloxacin
500 mg twice a day by mouth for 7 days.
Do not pinch, pop or squeeze any lesion as it can cause scarring. It will be alright in next few weeks if you are not disturbing it.
