Jock itch is a form of fungal infection also known as groin ringworm. It can be caused by a variety of fungi and yeast. It is more common in men than women. It produces red, ring-like areas on the skin, sometimes small blisters are present around the groin and over the upper and inner thighs. The condition can be quite itchy, even painful.
Recurrence is common because the fungi can survive indefinitely on the skin.
Even with proper treatment, a susceptible person may have repeated infections. Most fungal skin infections are cured with antifungal creams. Many effective antifungal creams can be purchased without a prescription. These ointments generally are applied twice a day and continued for seven to 10 days after the rash completely disappears. If the cream is stopped too soon, the infection may not be eradicated.
