Let us say technically, clinically, biologically, and physiologically, NO. However, it is physically possible although athlete’s foot does not lead to gangrene. Let’s try the explanation again.
Athlete’s foot fungus is tinea pedis. Gangrene is caused by an anaerobic bacteria called clostridia found in soil.
Athlete’s foot left untreated, athlete’s foot fungus that is allowed to grow into the flesh between the toes creates an open wound between the toes. If the open wound is not treated, the raw flesh of the open wound will bleed. The skin surrounding the open wound is dry and white, very white in color. Athlete’s foot itches and makes the foot “burn.”
Tinea corporis on the hand makes the skin of the palm hard and dry and white, as if there is a thick layer of white powdery and scaly skin. Tinea corporis on the fingers and palms will harden the skin, and eventually make the skin crack. Raw flesh will be exposed. And many dermatologists do not know how to treat dry, cracked up skin and open wounds on the hands with raw flesh exposed.
Notice, tinea pedis and tinea corporis do not create blisters and foul smelling pus. Although they do produce rather unpleasant foot odor and “smelly feet” or “fishy smelling feet”.
Clostridia is an anaerobic bacteria that invades an already open wound, goes under the skin, creates foul smelling pus and blisters, enhances its anaerobic environment under your skin by killing the skin and the skin turns brown and then green. Green skin has no oxygen in it. Gangrene blisters may or may not really hurt. They do not itch.
The only possibility for athlete’s foot to become gangrene is if the athlete’s foot is not treated, and an open wound develops, and the wound is not treated, and one does not expose the wound to the open air but continue to wrap it in tight socks and enclosed shoes, thus allowing the wound to fester. The shoes and socks that pick up dirt also pick up the clostridia bacteria in the soil. This clostridia bacteria wants to find an anaerobic environment, not necessarily a naturally moist environment. Tinea pedis looks for moist and dark environments where there is no sunshine and open air.
Tinea pedis stays between the toes. Clostridia spreads from the open wound that it just invaded. The first thing clostridia does is to create a blister and produce foul smelling pus. The smell of the gangrene pus is very different from the “fishy smell of althlete foot”.
Athlete’s foot remains white in color. Gangrene turns surrounding skin brown and then green. The white dead skin around athlete’s foot is dry and flaky, but has lost its strong odor. Dirty socks worn by someone with athlete’s foot will stink and smell fishy. Gauze wrapped around a gangrene sore will smell only if there is pus on the gauze.
Again, athlete’s foot does not become gangrene. It is the failure of the sufferer to treat athlete’s foot in time and allowing the open athlete’s foot wound to fester, to leave it unwashed with either water, hydrogen peroxide, vinegar, or soap, to continue to wear shoes and socks that completely enclose the foot, keeping the foot and its open and festering wound enclosed, wet, unwashed, that allows the clostridia in the dirty socks, dirty shoes, to invade the already open wound.
Washing and scrubbing the crotch, the feet, the skin, with a lot of cheap soap, it does not really matter as long as it is soap, will get rid of tinea pedis and tinea corporis very effectively. The indication is that the crotch, the skin, the feet, do not itch anymore for a day or two if you washed yourself and scrubbed yourself really hard or after such a heavy washing and scrubbing.
Tinea corporis on the palm of the hand that has already made the skin of the hand feel hard, powdery, and there are cracked skin and open cracks that bleed, water and soap, topical medical creams, antibiotics will not work.
The only thing that will work is hydrogen peroxide. Wash the hands in hydrogen peroxide again and again until a white film remains on the skin and the skin feels soft again, and the open crack on the hand closes and heals.
