How do I cure a scratch/scrape? - blading lessons

I want step by step, how to heal a scratch / embarrassment. I just went for my lesson in speed skating and had a big drop, my knee is a mess, and I know I'm clean. After that, I still open to provide a kind of balm on it, or what? This would help many can cause itching. Thank you ...
