I'm 29 years old female, i've got infection in my left armpit due to ingrown hair. Last time when it happened 4 years back, my doctor removed the pus with injection from the boil that has appeared below that ingrown hair, now i've observed last night 5 very small boils underneath it. Suggest me some medicine to treat the infection so it doesn't spread more neither the boils increase further. Plus also suggest if I should visit some doctor or dermatologist to permanently remove those remains of ingrown hair which is causing infection again and again.
