Overview of jock itch
Jock itch (tinea cruris) is a fungal infection that causes a red, itchy rash in warm and moist areas of the body. The rash most often affects the groin area and the inside of the thighs and may form a ring.
Jock itch got its name because it is common among athletes. It’s additionally regular in individuals who sweat a great deal or who are overweight.
Although jock itch is often uncomfortable and bothersome, it is not usually dangerous. Treatment may include keeping the groin area clean and dry and applying anti-fungal medications to the affected skin.
Symptoms of jock itch
Jock itch usually starts with a red area of skin in the crease of the groin. It often spreads to the upper thigh in the form of a half-moon. The rash may be ring-shaped and bordered by a line of small blisters. It may burn or itch, and the skin may be flaky or peeling.
What causes jock itch?
It is brought about by a gathering of growths called dermatophytes. These fungi live naturally on your skin and are not usually problematic. However, when kept in sweaty clothes after a workout, prolonged exposure to moisture can allow the fungi to multiply quickly. When you have an overgrowth of dermatophytes in the groin area, it causes an infection known as jock itch.
The fungi that cause jock itch are highly contagious. You may get contaminated with a contagious disease through close to home contact with a tainted individual or through contact with the unwashed attire of a tainted individual. The term “jock itch” might give the impression that only athletes are infected, but it can happen to anyone.
Those who are overweight are more likely to develop jock itch because the fungus can thrive in folds of skin that are prone to sweating. As a precaution, it is important to wash with soap and water on the groin and underarm areas daily. Jock itch may also be caused by prolonged exposure to moisture and friction from clothing.
Your doctor may be able to diagnose it by looking at the rash and hearing the symptoms. In rare cases, they may take a sample of the skin so the technician can look at it under a microscope.
Complications are rare because it is usually a self-limiting skin condition. In rare cases, the rash may spread beyond the groin to the thighs and genitals. A secondary skin infection resulting from uncommonly scratching or rubbing can deepen, leading to cellulitis or abscess formation.
Other potential complications include temporary skin discolouration called post-inflammatory hypopigmentation (lighter than normal skin colour) or hyperpigmentation (darker than normal skin colour). This discolouration of the skin may occur after the rash has improved or after a temporary flare. Permanent scarring is uncommon.
If jock itch is not treated, it may last for months. But over-the-counter medications called antifungals can usually clear them up within a few weeks. It’s available in creams, powders, and sprays.
Keep the area clean and dry. Take these steps for faster recovery:
- Wash the area, then dry it with a clean towel.
- Use a different towel on the rest of your body.
- Read the medication label, and use the medication as directed.
- Use it for as long as it recommends; The infection may return sooner if it is stopped.
Talk to your doctor if you do not feel better within two weeks. You may need stronger medication.
While jock itch itself is not dangerous, it can be a persistent and recurring problem that causes discomfort and itching. It does not cause any long-term damage, but rashes and other associated rashes such as athlete’s foot tend to recur if proper preventive measures are not taken.
The best way to avoid or prevent this disease is to dry carefully and wear clean, dry clothes after using public bathing facilities or a dressing room. Make sure to wash your clothes after each exposure. Sweaty or damp clothing stuffed in a bag is the perfect environment for fungus to thrive.
