I once had an ingrowing big toenail removed, and the advice was to leave it uncovered as much as possible, but maybe put a dressing on it when in bed (so it doesn't rub on the bedclothes). During the day, I wore old slipons with a hole cut for the big bandage, and in the evenings I left it uncovered. After about a month a new nail started to grow and I could wear ordinary shoes. I went back the to GP just once, after about a week, to have the original dressing changed. After that, I was on my own, and it worked out OK.
