Trench foot
The mainstay of treatment, like the treatment of gangrene, is surgical debridement, and often includes amputation. Self-treatment consists of changing socks two or three times a day and usage of plenty of talcum powder. Wherever possible, shoes and socks should be taken off, feet bathed for five minutes, patted dry, talcum powder applied and feet elevated to let air get to them.
