Will it grow back?

Today don't know what's wromg with me. I woke up at 5.30am. Since I came back from overseas, this is the first time i ever wake up so early. But it also shows one sign. I am kicking the habit of waking up late. Initially, I intended to go k with dell and lao da. But my huang hou don't want me to go. She even asked me to go to the regional library. Plus, my leg injured. One of my toe nail had been plucked up. Since that time after the training. But toe nail had been in pain. Then slowly thepain subsided. I thought my nail had recovered. Who knows beyond the nail, internal bleeding occurred. It was found out by my sister when she asked me why that one of my toe nail became brown colour and had no feeling at all. so in the morning about 8 plus, i went to pluck it out. So that a new nail will grow and also get rid of the harden blood. But surprisingly when I pluck it out, i did not feel any pain and there wasn't any bleeding when it supposed to have. Weird ar. Now I have to change the dressing about 5-6 hours interval. Hopefully the nail will grow fast. or else i cannot wear shoe for a long period of time.
