Ringworm (Tinea Corporis)

Ringworm (also known as jock itch) is a common fungal skin infection of the groin. Sometimes doctors call it the medical term tinea cruris - we should be clear it has nothing to do with worms! This fungal infection usually occurs in warm, moist areas such as the groin or in the armpit area or feet (where it is called tinea pedis or athlete's foot. It produces symptoms of a rash that is usually red, sore and itchy and has clear edges that can form a ring-like pattern. It is commonly found in athletes and the elderly but can affect anyone. When it is found in the crease of the groin it can spread a short way down the upper thigh.

The majority of cases are mild and can be treated easily with over-the-counter antifungal creams available from your pharmacy. If the medication is for a child, you should check with your pharmacist about the most appropriate over-the-counter medication.

There are a number of different antifungal creams available (you will see names such as terbinafine, clotrimazole, tolnaftate, and miconazole), so check the directions that come with each cream as it will tell you how often and for how long to use it. Apply the cream to the affected area and to the non-affected skin that is up to 2 inches around the affected area.
