Ouch! I'm not a doc and asking your PCP is prob the best way to get professional input but here's what I know about this. My BF had the very same thing happening to him (also with the Nepals). There is no real treatment but tough it out and wait for the new nail to grow. Make sure to keep the nail nice and clean to avoid any infections on top of it.
How did that happen? Do you think your nails were a little too long? Anyways, have a speedy recovery!
