Re: toenail removal
What exactly was done? Was just the ingrown part cut out, or was the whole nail removed?
No personal experience here, but:
If there's pus involved, sometimes the doctor prescribes an antibiotic ointment to put on the toe. But soaks in warm salt water are really the best thing. Try doing it 2-3 times a day if feasible.
Definitely, she should be wearing loose or open toed shoes. Cover the toe with gauze if it's ugly, but don't cover it with a tight, non-breathable shoe.
It might be a couple weeks before it feels right, but I would call your doctor again if the pus doesn't go away in a couple more days.
