Jock itch is a common fungal (caused by a fungus) infection similar to ringworm. Jock itch causes an itchy, stinging, burning rash on the skin around your groin, inner thighs and butt crack (gluteal cleft). Tinea cruris is another name for jock itch. Tinea is another name for ringworm, and cruris means groin.
With this infection, your skin may become scaly and cracked or develop bumps or blisters.

Symptoms and Causes

What causes jock itch?
A fungus causes jock itch. A jock itch rash is ringworm. Ringworm can look like circles. But an actual worm doesn’t cause ringworm.
Is jock itch contagious?
Jock itch is contagious. Jock itch is a fungus that grows on or in your skin. Fungi (plural form of fungus) need warm temperatures and moisture to grow. Tight underwear or pants trap heat and moisture around your groin. Heat and moisture create the perfect environment for jock itch to grow.
How does jock itch spread?
Jock itch commonly spreads through skin-to-skin contact or contact with an infected surface. You can get jock itch through sexual contact with an infected person. You can also get jock itch by sharing towels or clothing with an infected person.
In some cases, you can get jock itch if you have athlete’s foot (tinea pedis). You can spread the fungus by touching your groin after touching your infected foot. You can also spread the fungus from your feet to your groin through your clothing. When getting dressed, it’s a good idea to put on your socks before your underwear to prevent spreading the fungus from your feet to your groin.
Diagnosis and Tests
How is jock itch diagnosed?
Your healthcare provider can typically diagnose jock itch by examining your groin and reviewing symptoms.
What tests will be done to diagnose jock itch?
In some cases, your healthcare provider may remove a small piece of skin (biopsy) and test it in a lab. Several drops of a potassium hydroxide (KOH) solution dissolve the skin cells so that only fungal cells are visible.
Management and Treatment
Will jock itch go away on its own?
Jock itch doesn’t typically go away on its own. If it’s left untreated, it can spread to other areas of your body, including your:
- Nails: Fungal nail infections can be more difficult to treat. They’re often more resistant to many treatments.
- Hands: A similar fungal infection can spread to your hands. This happens when you scratch your infected groin with your hands or use the same towel to dry off both areas.
- Feet: The same fungus that causes jock itch can also spread to your feet. It’s a condition called athlete’s foot. The fungus typically spreads from your groin to your feet through your underwear. It can also spread by using the same towel to dry off both areas.
How is jock itch treated?
It’s important to finish your full course of medicine. If you stop too soon, your jock itch may come back and be harder to treat.
What is the fastest way to cure jock itch?
The fastest way to cure jock itch is to use an OTC or prescription antifungal cream, ointment, gel, spray or powder. In more serious cases, your healthcare provider may prescribe antifungal pills to treat jock itch.
For faster recovery, it’s also important to keep the area clean, dry and cool.
Can rubbing alcohol cure jock itch?
Rubbing alcohol may help cure mild jock itch. Rubbing alcohol can prevent or stop fungal growth on the surface of your skin. However, rubbing alcohol can make your skin dry and tight, and it can make irritation worse.
Are there any home remedies for jock itch?
In addition to rubbing alcohol, a few home remedies may help prevent or treat jock itch.
Some essential oils can prevent or stop the growth of bacteria. These include tea tree, bitter orange, peppermint and eucalyptus oils. However, they may not completely get rid of a fungal infection.
Garlic contains a compound called ajoene. Ajoene can prevent or stop the growth of bacteria. But, like essential oils, it may not completely get rid of a fungal infection.
If you’re allergic to essential oils or garlic, don’t use them to treat your jock itch.
How do I manage my jock itch symptoms?
Keep your groin dry, clean and cool. Use a powder or spray to absorb moisture around your groin, particularly after bathing or working out. Avoid wearing tight underwear or pants. Avoid scratching your groin. Scratching your groin may cause the fungus to spread to other parts of your body.
How soon after treatment will I feel better?
With proper diagnosis and treatment, your jock itch should go away in one to eight weeks. And, be sure to follow your healthcare provider’s instructions.
It’s also important to finish your full course of medicine. During the early healing stages, itchiness and irritation will fade. Even if your symptoms go away, you may still have jock itch. If you don’t finish your full course of medicine, your jock itch can come back and be harder to treat.
How can I reduce my risk?
There are many ways to reduce your risk of getting jock itch:
- Thoroughly wash your groin with antibacterial soap.
- Dry your groin after swimming or bathing.
- Apply talcum powder or antifungal powder to your groin to absorb moisture.
- Wear loose underwear and pants that allow the area to breathe.
- Wear cotton underwear to absorb moisture or underwear made out of synthetic materials to wick away moisture.
- Wash your clothes after use, especially the clothes you wear while working out.
- Don’t share towels or clothes with others.
How can I prevent this?
If you have athlete’s foot or another type of fungus, there are many ways to prevent yourself from getting jock itch:
- Treat your infected area with antifungal creams, ointments, gels, sprays or powders.
- Use a separate towel to dry your infected areas, or dry any infected areas last.
- When dressing, put on your socks before your underwear.
- Avoid scratching your infected areas. If you must scratch an infected area, thoroughly wash your hands with antibacterial soap before touching any other parts of your body.
- Wash your socks, underwear, towels and bedding in hot water.
- Avoid sexual contact with anyone who has jock itch until it’s gone.
