What Is Jock Itch?
Jock itch is a common fungal skin infection that affects the groin, inner thighs and sometimes the crease of the buttocks. Doctors call it tinea cruris,¹ and while symptoms can vary from one man to the next, they often include:
- A red, brown, purple, or gray rash that spreads from the groin down the upper thigh and buttocks²
- Itching or a burning sensation
- Flaky or scaly skin
- A rash with a slightly raised or blistered border
- Jock itch can often have a distinct musty odor.¹ When you sweat, bacteria that naturally live on your skin add to the odor.
Because many rashes can look and feel similar, it's best to see your doctor for the correct diagnosis.
What Causes Jock Itch?
Jock itch is caused by a fungus that loves moist areas of the body² like skin folds. This makes the groin a perfect environment. Men who sweat heavily, are active, and play contact sports are more likely to develop jock itch.
How to Get Rid of Jock Itch
This fungal infection won't go away on its own and can easily spread to other areas like your hands and nails.³ That's why you should see your doctor. Once they've examined you, they will likely recommend over-the-counter antifungal creams, prescription creams or even tablets.
In the beginning you'll notice the discomfort is less. But just because the rash is better or you're not as itchy doesn't mean you're rid of jock itch. Follow your doctor's instructions and finish the course of medication or creams to prevent jock itch from coming back. In general, the infection should clear up within one to eight weeks.³
Cleansing When You Have Jock Itch
When irritation and odor show up, the instinct is to wash more and scrub harder. Resist it. Harsh cleansing and showering more than once or twice a day can strip your skin barrier and make things worse, not better.
Use gentle cleansers
Look for a mild, sulfate-free body wash that removes sweat and odor without stripping your skin. Wash the groin area last.
Watch the water temperature
Hot water can dry out already irritated skin. Stick to lukewarm water and a light touch on the inner thighs, groin folds, and buttocks.
Skip the loofah
Rough washcloths or aggressive scrubbing tools can irritate already sensitive skin. Use your hands and wash the area gently.
Rinse well
Leftover body wash in the skin folds can cause its own irritation, so take an extra moment to rinse thoroughly.
Pat dry, don't rub
A clean towel and a gentle pat is all you need. Rubbing adds friction exactly where you don't want it.
Daily Habits to Prevent Jock Itch From Coming Back
Once you've managed to beat jock itch, you'll want to prevent it from coming back. Here are some easy habits that also help to keep the area feeling fresh.
Stay clean and dry
Shower after workouts or heavy sweating, dry thoroughly in skin folds, and change out of damp underwear or gym gear as soon as you can.
Don't share personal items
Don't let others use your towel or borrow theirs.
Avoid walking barefoot
Walking barefoot in public places or public showers can increase the risk of picking up athlete's foot, which can be transferred to your groin through clothing, towels or your hands.
Choose breathable fabrics
Wear cotton underwear or boxer shorts, loose sleep shorts, moisture-wicking workout gear, and avoid tight fits.
Protect your skin barrier
A gentle, sulfate-free, moisturizing body wash is your friend. Skip strong fragrances or harsh soaps and go easy on powders or sprays if your skin is already irritated.
Choose gentle odor-tackling formulas
Once the infection has cleared and the skin has completely healed, a gentle aluminum-free deodorant made for the whole body, including the groin area, can help with odor.
Look for a formula that's dermatologist-tested and follow the directions. Check with your doctor if you're unsure.
FAQs
Your doctor may recommend an over-the-counter antifungal cream as a first step, or a prescription treatment if needed. Keep up with daily washing using a gentle body wash or cleansing bar, pat dry, don't rub, and wear breathable fabrics.
A few common culprits: moisture that's trapped in skin folds, tight clothing holding sweat against the skin, natural bacteria or not drying off completely. If the smell won't quit, your doctor can help you figure out whether jock itch or another skin condition is behind it.
Use lukewarm water, a small amount of gentle body wash, and your hands. Rinse completely and pat dry instead of rubbing. Stop if cleansing causes discomfort and speak to your doctor.
Jock itch is uncomfortable, but it's an infection you can tackle with the right know-how. See your doctor, follow the treatment through, and keep up the daily habits that stop it from coming back. Within a few weeks you should feel like your old self.
