i had a boil for the first time in my life . I am 39 years old. i had an under arm boil around thanksgiving it was only one. then soon after putting ichthammoll ointment it came to a head and drained then not long after that i felt about 3 to 4 small other ones  they are not painful but i have been putting that same cream on it  they appear to be doing better but what i want to know is what can i do to not get this again and is this normal to have several small ones under my armpit after the one that healed?
Dear Sir/ mam, Here is the answer for your question. Boil is an infection of the hair follicle. They are common in the areas where there is increased hair and sweating. Occurs because of decreased aeration in the region. Deep shaving also causes this. The ointment you use is the one which softens and decreases the pain. An antibiotic ointment like nadifloxacin is preferred to ichthammoll. I would also recommend to wear loose garments. Kindly get back for further info and give rating if you find this answer worthy
