I frequently get boils on labia minora. Like once or twice a month. It looks like a pimple and is painful. It sometimes itches around that pimple like a strong urge to scratch. Sometimes it goes away in 3-4 days by itself. Sometimes it takes 8-10 days to go, the one that stays for a longer duration usually has pus and it bursts with pus and blood before it becomes really normal. I have never taken medicine for this, I have usually tried warm water compress or waited for it to disappear. I don't know why it is so frequent. And what should I do about it. Please help.
