While I agree with much of what cocosandy, I would keep the wound open and let it heal from the inside out. You can cut strips of gauze and soak in pennG then push that gauze into wound. Bandage foot to keep it clean. The before next soak, remove gauze and soak foot. When you remove gauze you will be cleaning out the wound. I would not leave gauze in any longer than 24 hrs. Keep us posted.
