This thing has been getting treated with tolnaftate cream and powder 2-3 times a day (plus the wash I described earlier) for about 2 weeks - but it is not getting better. It's worse - not just the wound area but also the itching and spreading to other parts of the foot...top and bottom.... and I am scared I'll spread it to other areas of my body too now...
