I've had severe toenail fungus for 18 years!

I've had severe toenail fungus for 18 years! I've tried everything. Finally this year, i feel like I'm seeing huge improvement. - castor oil, tea tree, tinactin cream and Jublia. Wow. Two weeks ago, rashes popped up on my groin, armpits and on my head. Great... athletes foot has spread I assume. I made a doc appt which I couldn't get in for three weeks. So in the mean time, I thought I'd just adapt my diet- 100% cut sugar, refined foods, and alcohol. I'm also taking a probiotic and a biotin supplement. The results have been incredible.
