Vagina injury

I didn't know where to post this. Last night. Me n husband were 69in' and he was fingering me too. It was great until his finger wound up missing the spot and stabbed my Virginia (that's what I named my vagina) with fingernail omg hurts. Does anyone know if there's a certain medicine I can put on it to make it feel better and not burn when I pee from the urine touching it
