I Did The Salt And Ice Challenge About Three Or

I did the salt and ice challenge about three or four days ago, and the day after I did it, the skin on my arm began to peel off. I've been applying alcohol and neosporin to it every day since then, as well as keeping it covered up with gauze pads. It still looks fleshy and it isn't showing any signs of healing and now I'm starting to get sort of nervous. Is there anything else I should do?
