Dont know how long, had an x-ray at 11.30 last night after waiting for 2 hours. This was after one huge heffa of a nurse that resembled one of matt's friday night play things had tried to bend the nail back with all her strength. Came really close to swinging for her! Got a little chip off the bone, but she said they dont usually cause much of a problem, just gotta wait for swelling and bruising to go so hopefully only a week or two.
