What is
Jock itch
The term "jock itch" typically describes an itchy
rash in a man's groin. Although there are many causes of jock
itch, this term has become synonymous with tinea cruris, a common
fungal infection that affects the groin and inner thighs of men
and women. Tinea is the name of the fungus; cruris comes from the
Latin word for leg.
Jock itch can develop when tight garments trap moisture and heat.
This creates an environment in which fungi multiply and flourish.
Athletes often get jock itch. It occurs more commonly in men, but
can affect women as well. The jock itch fungus may cause a rash on
the upper and inner thighs, the armpits, and the area just
underneath the breasts. Many people with tinea cruris also have
athlete's foot. Athlete's foot is called tinea pedis.
Symptoms
A flat, red, itchy rash first appears high on the inner side of
one or both thighs. It spreads outward in a ringlike circular
pattern while the center clears up partially. The border is
sharply marked, slightly raised and often beefy red in color. Jock
itch can spread to the pubic and genital regions and sometimes to
the buttocks.
Diagnosis
Your doctor often can make the diagnosis just by looking at the
rash. Your doctor may gently scrape the skin to get a sample to
look for fungi under the microscope. With stubborn cases, your
doctor may send the sample to a laboratory to pinpoint the fungus
that's causing the trouble. Other causes of a rash in the groin
include yeast infection of the skin, seborrheic dermatitis and
psoriasis.
Prevention
The healthier you are, the less likely you are to get a fungal
infection. Remaining healthy through diet, rest and exercise is
the first step in avoiding fungal infection.
Here are other steps you can take to remain fungus-free:
* Keep your body clean.
* Dry yourself well after showers and baths.
* Shower immediately after athletic activities.
* Wear loose clothing whenever possible.
* Do not share clothing or towels with others; wash towels
frequently.
* Clean exercise equipment before use.
* Wear sandals in the shower area at the gym and swimming pool.
Treatment
Most likely, your doctor will prescribe a topical antifungal
treatment for you to apply once or twice a day for at least two
weeks. If you have athlete's foot, your doctor should treat that
as well. Untreated athlete's foot can cause jock itch to return.
Because jock itch commonly comes back, you need to be extra
cautious. You can apply powder daily to help keep the area dry.
The itching can be alleviated with an over-the-counter treatment
such as Sarna lotion. You also should avoid hot baths and
tight-fitting clothing. Men should wear boxer shorts rather than
briefs.
