I'm sure you've tried the anti-fungal creams if you've had it for a while...are you sure that it's ring-worm? If so you could try papaya, rub the slices (don't rub too hard) on the affected areas a couple times a day. Clear nail enamel, apply to area, leave on all day & then remove it by placing a cotton ball soaked with nail polish remover on the area for 5 or so minutes. Tea tree oil is also a cure-all...it definitely works for fungus! Hope that helps.
