I went low for a half volley, my knee scraped and was bleed I have a 1in. dia. cut, scab form around about 1cm in, it starts to get moist when it bends like in bed or when I play, I havent taken any days off since it happened.. started puting iodine on it.. any suggestions? it just keeps opening... theres like a film that forms on it but it rips off... weird.. any cream I should buy or something? I need to get it to heal in about 5 days I have a match, cant really bend my knee with scab or something there... please help me... its annoying!
