Sounds as though you may have developed a fissure, or something like it. NO BIGGIE, unless it's really deep, which you didn't mention. In many situations they heal on their own. Analpram is a steroid, as you said, and with prolonged use thins the skin. So be careful with it.
If I were you, I would be using a tripple antibiotic ointment such as "Neosporin plus" which has a pain reliever in it. The generic version is fine. You can also put the steroid on first.
Good Luck. It should close up within a week or so.
