How do you Treat Foot Rot?

Depends on what kind of foot rot it is. Feet run into a lot of fungal infections. For this, an anti-fungal cream and, if you can, keep the foot exposed and dry. If you have to wear socks during this period, change to fresh socks twice a day AND whenever your feet get wet. If you shower, wash your feet thoroughly, dry and reapply ointment as per presciption. Note that fungal infections are contagious. Bleach works wonders on killing off fungii, so that would be a good disinfectant for the shower and your clothing, but not for your bod. If you're in civilization, keep the feet clean, dry as much as possible, open to the air when you can, and medicated. When you're in the field, focus on healing the rot with creams or in some cases powders (anti-fungal), and keeping the feet DRY. In extreme cases, you may need to resort to systemic anti-fungals.
