My grandfather taught me to "thump it" when you smash a finger nail.
It keeps the blood flowing. It makes you about wet yourself but never turns black and never falls off. Can you be a bit more specific on the "thump it" ?   Use your middle finger on your opposing hand like you would if you were going to "thump" a watermelon or someone on the head.
