A few months ago I seemed to get a bit of a lump that was incredibly sore indeed. It got to the point where even sitting down was hard. The lump was just inside the hole and went away after a 2 days or so.
Its not come back since, and I clean around that area throughly as I do a lot of exercise.
Could this have just been me not quite getting in to the nooks and crannys properly when I bathed/showered?
