For the past 6 months or more, I ve noticed that within 2-4 days before getting my period, I develop a boil or skin furnuncle pretty much in the same exact spot on my outer labia every month. I asked my doctor about it when I last went and she simply said it might have something to do with my hormones affecting my immune system, which was what I d guessed myself. But she didn t give me any sort of recommendation on how to treat it. I was wondering if anyone else has had this problem and if they know of any way to make the boils stop forming? It s fairly painful and I end up putting a band-aid on it. It eventually drains, but it s very frustrating.
