is jock itch?
Tinea cruris, most commonly known as jock itch, is a fungal
infection of the skin. It belongs to a group of fungal skin infections
called tinea. Like other tinea infections, jock itch is caused by
mold-like fungi, which are known as dermatophytes. These microscopic fungi
naturally live on the skin as well as on the hair and nails. They’re typically
harmless, but they can multiply quickly and cause infections when they’re
allowed to thrive in warm, moist areas. This is why jock itch usually develops
in the skin around the groin, inner thighs, and buttocks.
Jock itch is most common in men and adolescent boys. The
infection causes a rash that often itches or burns. The affected areas can also
be red, flaky, or scaly.
It’s also more frequently seen in the homeless, as they do not
wash with soap and water in the groin and armpit areas as regularly.
Though jock itch can be bothersome, it’s typically a mild
infection. Treating it quickly will minimize symptoms and keep the infection
from spreading. Most people find relief simply by applying topical antifungal
medications and by keeping the affected area clean and dry.
are the symptoms of jock itch?
Common symptoms of jock itch include:
- redness in the affected area
- persistent itching in the affected area
- burning sensation in the affected area
- flaking, peeling, or cracking skin in the
- a rash that gets worse with exercise or activity
- changes in skin color
- a rash that does not improve or even worsens or
spreads with over-the-counter hydrocortisone (anti-itch) cream
Jock itch typically affects the groin and inner thighs. It may
spread to the abdomen and buttocks, but the scrotum usually isn’t affected.
causes jock itch?
Jock itch is caused by a group of fungi called dermatophytes.
These fungi naturally live on your skin and normally don’t cause problems.
However, when you remain in sweat-soaked clothes after exercising, the lengthy
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 jock itch is highly contagious. You may
get the fungal infection through close personal contact with an infected person
or through contact with the unwashed clothing of an infected person.
The term “jock itch” may give the impression that only athletes
develop the infection, but it can occur in anyone. Those who are overweight are
more likely to experience jock itch because the fungus can thrive in folds of
skin, which are prone to sweating. As a preventive measure, it is important to
wash with soap and water in the groin and armpit areas daily. Jock itch may
also be triggered by prolonged exposure to moisture and friction from clothes.
is jock itch diagnosed?
Your doctor will likely be able to diagnose jock itch simply by
performing a physical exam and inspecting the affected area of skin. In some
cases, your doctor may take some scrapings of skin cells from the area to help
with diagnosing the condition. This may also help rule out other skin
disorders, such as psoriasis.
is jock itch treated?
In most cases, jock itch can be treated at home effectively. You
can try the following remedies to get rid of the infection:
- Apply an over-the-counter antifungal cream,
powder, or spray to the affected area.
- Again, using an over-the-counter anti-itch cream
like hydrocortisone (steroid cream) will make jock itch worse.
- Wash the affected area thoroughly with soap and
- Dry the affected area thoroughly after bathing
- Change clothes and undergarments every day.
- Wear loose cotton clothing.
- Treat any other fungal infections, such as athlete’s
should I see my doctor about jock itch?
If your symptoms don’t improve after two weeks of home
treatments, you should make an appointment to see your doctor. You may have
developed a secondary infection that needs prompt treatment.
If you do have jock itch, but it’s not responding to
over-the-counter medications and home remedies, your doctor may prescribe
something stronger. Possible medications include:
Oral antifungal medications may cause unpleasant side effects,
such as upset stomach and headaches. If you experience any of these side
effects, make sure to discuss them with your doctor.
can jock itch be prevented?
Practicing good hygiene is the best defense against jock itch. Regular hand-washing can
greatly reduce your risk of getting this infection from someone else. It’s also
important to keep your skin clean and dry, especially the area around your
groin. Wash the area regularly with soap and dry the area thoroughly after
bathing. Applying baby powder around the groin can also be helpful for
preventing excess moisture.
Avoiding tight-fitting clothing further reduces your risk of
getting jock itch. Tight clothes can rub or chafe your skin, which makes you
more susceptible to jock itch. You may want to try wearing boxer shorts instead
of boxer briefs. It’s also beneficial to wear loose-fitting clothing in hot or
humid weather. Loose clothing can prevent sweating and the warm, moist environment
in which fungus thrives. Make sure you wash any workout clothes or athletic
supporters after each use.
Athlete’s foot is another infection that can be caused by the
same fungi that cause jock itch. If you have athlete’s foot, treat it quickly.
You can avoid spreading it to your groin area by making sure you don’t use the
same towel you use on your feet for your groin.
