I no longer have a cycle and haven t for years. But it seems when it was supposed to be that time, I develop a reddish boil under the skin in the pubic area. I feel it under the skin long before the size develops. I do shave, however it then forms a boil-like object in this area, and begins to hurt very much. Swells up and I apply neosporin and peroxide but it takes awhile for a head to form. Quite painful before it burst. Why is it happening and what can I do to prevent future occurrence
