I think it was a week or so where I had to have it wrapped and couldn't wear a normal shoe. After that a simple bandage and regular shoe for a little while. It took months for the nail to grow back but after about 2 weeks (I think) it wasn't sensitive to the touch anymore.

I don't remember anything about chemicals to kill the nail bed...they gave me a shot to freeze the toe before removal...that was the worst part of the whole procedure for me. They did put some sort of goo on my toe after removal...I thought it was just liquid bandage or something like that but I guess it could have been something that killed the nail bed...I didn't ask and wasn't told about it beforehand.
