tinea pedis
"According to the manufacturer and my dermatologist, this gel does not get absorbed by the skin, hence will not cause systemic side effects.  Experience says otherwise.  After applying it to my athlete's foot, including infected toenail, I became extremely dizzy.  The side effect disappeared upon discontinuance.  Later, the fungus spread to my groin, so I thought I would give the gel another try.  Again, I became very dizzy so washed it off.  I recovered immediately upon doing so."
