Not a Fungus...: Callus on a toe is often mistaken for a wart infection on the toe. A callus is caused by pressure and a wart is caused by a virus infection. Either way, avc (sulfanilamide) will not work against either condition. Since callus really doesn't spread, so to speak, a wart is more likely. Either consult with your doctor or a Healthtap specialist for diagnosis and treatment.
