Alternative Medicine
 
Myrrh - http://www.anniesremedy.com/herb_detail38.php - "Most of the internationally-traded myrrh and frankincense are produced in the southern Arabian peninsula (Oman, Yemen) and in northeast Africa (Somalia). The primary species relied upon today are Commiphora myrrha for myrrh and Boswellia caraterii for frankincense...(Related Species Commiphora wightii : Guggal, Guggul or Mukul myrrh tree - Endangered species used in traditional Ayurvedic medicine. The collective name Guggul can also be used to refer to myrrh, frankincense and other gum resin trees of Africa to central Asia.) "  [Such applications can be as supplements or as anointing oil (externally), etc.]
 

External Remedies
 
Copper - http://www.arthurleej.com/Violet.pdf - BENEFICIAL IONS -  Leej, Arthur - "Copper is the most fungicidal of the metals and can be used for infections. Until 1940, copper salts were used for the treatment of chronic cervicitis. The copper has a toxic effect and the area to which it was applied sloughed off about a week later. The treatments were repeated at intervals of 10-14 days.
One of the important applications of ‘ionic surgery’ was the treatment of fungus infections of the hands and feet. Athlete’s foot is particularly difficult to treat. The fungus embeds itself deep into the skin, and topical remedies don’t penetrate enough to kill it. After the person stops using the ointments, the athlete’s foot fungus returns to the surface and the cycle goes on.
Copper is highly toxic to fungi, but soaking the feet in copper sulfate doesn’t do any good. (Then) Electrically applied copper was tried in 150 37 patients with dermatophytosis with long-lasting infections. They soaked their feet in enamel pans for 20 minutes while a current of 6 ma. was applied. A special circuit slowly built up the current when the hands and feet were immersed. This took care of shocks.  The average number of treatments to stop the problem was about 6, but the total number of treatments ranged from 4-18 over 8 weeks. A few people weren’t cured, but the feet were greatly improved, and the cure simply took more treatments. The doctors tried treating only 1 foot in several patients as a check, but the other foot didn’t improve in a common salt solution. After a few copper ion treatments, the feet began to stop sweating. 
One patient had vesicles on his feet for 25 years. He walked on crutches for 7 months and had been unable to do much of anything, because of blisters on his hands. When copper ionization was applied to his hands and feet, improvement was rapid and steady."
Consider wearing socks with copper threads and/or copper anklets, to determine if that might work for you.
