Subterranean Homesick Zit

I don't get normal acne. I get these weird underground burrowing zits that never come to the surface in any reasonable zittish fashion but stay under the skin and form little planets, little meteorites that never really go away and always hurt. They are sometimes invisible to the naked eye or sometimes they make themselves known as large welts on my face. I never had zits as a teenager and only now in the twilight of my life do I find myself with a recurring situation that is only receptive to cortisone shots from the dermatologist.

I wonder if I will still be able to participate in the Olympics if I get a cortisone shot for my subterranean spot.

PS What ever happened to Oxy 10?
