Tinea cruris, most known as jock itch, is a fungal infection of the skin. It belongs to a group of fungal skin infections called tinea. These microscopic fungi live on your skin, hair, and nails.
The fungus that causes jock itch is highly contagious.
They are typically harmless, but they can multiply quickly and cause infections when they are allowed to thrive in warm, moist areas. That is why jock itch usually develops in the skin around the groin, inner thighs, and buttocks.
The infection causes a rash that often itches or burns.
If the following factors apply to you, you might have a higher risk of jock itch:
You are male.
You are a teenager.
You are overweight or live with obesity.
You tend to sweat.
A group of fungi called dermatophytes cause tinea. These fungi naturally live on your skin and typically do not cause problems. However, when you remain in sweat-soaked clothes after exercising, prolonged exposure to moisture can allow the fungi to multiply quickly.
When you have an overgrowth of dermatophytes in your groin area, it causes the infection known as jock itch.
The fungus that causes itch is highly contagious. You may get the fungal infection through close personal contact with a person who is suffering from it or through contact with that person’s unwashed clothing.
- Persistent itching
- Burning sensation
- Flaking, peeling, or cracking skin
- Rash that gets worse with exercise or activity.
- In most cases, you can treat jock itch using several at-home products. You can try the following remedies to get rid of the infection:
- Apply an over-the-counter (OTC) antifungal cream, powder, or spray to the affected area.
- Wash the affected area thoroughly with soap and warm water.
- Dry the affected area thoroughly after bathing and exercise.
- Change clothes and undergarments every day.
- Wear loose cotton clothing.
If you take OTC medications or use home remedies and symptoms do not improve, a healthcare professional may prescribe something stronger. Viable options include topical or oral medications.
Topical medications include econazole (Ecoza) or oxiconazole (Oxistat), while oral medications include itraconazole (Sporanox) or fluconazole (Diflucan).
Just take care of your hygiene to remain healthy in all means.
Best of luck!
