Wat is ringworm?

Ringworm: Ringworm is the common or lay term for a common superficial infection of the skin caused by a fungus (actually several types of fungus). It's name comes from the fact that the fungus tends to cause a circular patch of scaling scan with a slightly raised and redder border making it look like a ring. It can be treated with ordinary otc anti-fungal medications.

Agree with Dr. K: If the OTC medication does not resolve the lesion in a week or so, you should see a doctor as the lesion may not be ring worm.
