Jock itch or tinea cruris is a common fungal infection which results in an itchy, red and often ring-shaped rash. It affects the warm, dark and moist areas of the body like the skin of genitals, inner thighs, and buttocks.
Although the infection is usually not serious, it is bothersome and causes a lot of discomfort to the patient. It is more common in people who sweat a lot, like athletes.
Sweat creates a warm and moist environment for fungus to easily thrive in. Thus, maintaining cleanliness of the groin areas is an effective way to reduce the chances of infection.
It's clinical treatment involves administration of antifungal drugs through oral route or local application.
The characteristic ring-shaped pattern of spread from the crease of the groin area towards the upper thigh.
The rash is characterized by the presence of raised blisters at the borders.
Itching or burning sensation in the affected area.
Scaly or flaky skin at the affected area.
It could be accompanied by athlete’s foot disease.
If over the counter medications do not cure the infection within two weeks, the patient should consult the doctor.
A dermophytic fungus is responsible for causing jock itch. The fungus is present on the skin normally but prolonged exposure to moisture and warmth in the groin or folded areas of the body, results in its overgrowth.
Continuous irritation or rubbing in the affected area worsens the infection. It is a communicable disease and thus can easily spread from one person to another by the shared use of contaminated towels or clothing.
As the same contagious fungus is responsible for athlete’s foot infection, there are chances that the fungus has somehow spread from feet to the groin area.
4 Making a Diagnosis
The doctor usually diagnoses the jock itch infection by simply looking at the affected area but in some complicated cases, microscopic examination of the skin scrap is needed.
In very rare cases, the doctor may also need to send the samples to the laboratory for culturing to rule out jock itch from other related infections.
