I'm finally cured from jock itch. Not treated, but cured.
First of all, I'll let you know what what I tried and how it worked.
Braggs ACV - ok for a few days. Diluted 50 % with water works best. Undiluted sting a lot. Still doesn't work long term for me.
Borax - didn't use a lot but seemed to work.
Lamisil - works good but fungus returned a week after stopping. I used the cream
Other otc creams - same as Lamisil
lemon - same as ACV
and finally what worked for me
non fat plain Greek yogurt applied liberally liberally 1 to 2 times a day for 3 days after shower. I use a blow dryer before applying yogurt. Sometimes I mix it with with prebiotic acacia Senegal and that does the trick.
Hope this helps someone with one of the most most embarrassing problem. Total cost is probably 50 cents!
