Recently, after a visit to the loo, I discovered a large solid feeling lump
under the surface of the skin in the area of the perineum
. Its been there for a few days, and seems to be getting more and more painful to the touch. I've tried to pop it, but it seems to be solidly rooted under the skin. I've had acne of this form on my face before, and when given time, the white head eventually emerges onto the skin surface. Is this mass/lump just a white head also?
