I mashed the top knuckle of a finger with a rock -- never mind the details, it was silly. Nothing was broken, but it hurt like crazy, turned purple black promptly. I applied ice, and so forth. It is now fully eight weeks later. The nail clearly is on the verge of departing. It has separated at the base and one side. There's about 1/4 inch (or 8 days) of normal nail at the top. When that's gone, the nail will go. Okay, my question: Do I just wait and see if the nail grows normally afterwards. Is there a chance that the nail won't grow at all?
