What to do for a skin infection?

Make sure you keep it clean. if it's got little pebbles or dirt in it still from the road, make sure you clean it really well (take a bath). and then really gently pat it dry with a clean towel. the gently blow at it, to cool it down and when you know it's dry, put a LITTLE rubbing alcohol on it to disinfect it. i know it stings and hurts to put the rubbing alcohol on, but you need it to disinfect it! don't but any bandages on it. instead, wear shorts that don't cover the knee (never have any fabric rubbing against it and don't touch it, unless you're cleaning it with a towel). also, take a multivitamin daily, because certain nutrients help with skin recovery. PS: whenever it itches, that means it's healing!
