Will my toenail grow back?

Yes, it will grow back. To get it to grow back straight and not painfully back into the skin, you might go to a salon and get a fake acrylic nail put on it. Keep it clean and within at most a year, you should have a perfect nail right under the acrylic one. This method is pretty much fool proof. If you dont want to go to the salon, you could improvise with *GOOD* fake glue on nails that you can get from even the dollar store. Good luck and hope your toe feels better!
