i had athletes foot, it seems to be seasonal and i think it flared up from wearing boots and shoes becuase i got it in the fall . i think it lives in boots and shoes if you have had it once it may be in the shoe.
i did the following for 6 weeks: AND it cleared up!
daily after shower i used Miconazole Nitrate 2% Powder Spray (WM has it cheap) and Desenex Powder and also Tea Tree oil on toes. Tea Tree stinks but use a q-tip to apply.
nightime you can use Desenex powder.
spray all boots and shoes with lysol spray and if there is a certain shoe that triggers the itching , discard them becuase the fungus lives in the shoe for a long time. just like mushrooms you dont see and then they pop in damp weather.
wash feet well before using these and dry well. wear sandals around the house if you can.
for toenail fungus. ugh. nothing seems to work. try cider vinegar soaks, creams, tea tree. Rx things like the Lamisil pills are bad for the liver. if they are lifting off the toe they need to be removed. all toes involved with fungus? see a foot doctor. don't wait like i did. having removal of three nails this week.
