Why won't jock itch go away?

[HadaraNight]

Hello, nice to meet you.
I am a young female and for about three months I've been fighting with a jock itch that will never go away.
I've already been to a dermatologist and he's tried with every medicine available: from ointments like ketokonazole to even oral antifungals, you name them: itraconazole, fluconazole, Terbinafina, everything! I've followed his right instructions and I have even changed my diet, avoiding sugars and flour,and eating tons of garlic, and yet it always reappears after two weeks. I've been avoiding tight clothing as well and only using cotton; I make sure I dry it well, and yet nothing works.
I am desperate. I don't want to keep taking antifungals because I'm afraid I may compromise my liver or something else but I also want to get rid of this before it spreads. I've asked my dermatologist about it, and he says he doesn't know what to do anymore and he only keeps giving me more medicine. What can I do?

Have you tried tea tree oil?  I know that tea tree oil seems to clear up a lot of those types of things- I'm not sure about specifically jock itch, but it might be worth a try.
