Medically termed as tinea cruris, it is a fungal infection of the skin in the groin region. People who wear sweaty, wet clothes during summer time or wear several layers of cloth during winter time are at an increased risk of suffering from jock itch. Warm, moist environment serves as the perfect breeding ground for the fungus. Men are more prone to suffering from this skin disease as compared to women. This rash starts in the groin fold usually on both sides. When the rash advances, it advances down the inner thigh. The advancing edge is reddish and raised as compared to areas that have been infected for a longer period of time. It is usually scaly and is easily distinguishable or demarcated.

This fungus breeds in moist, warm water and therefore it occurs in the groin area and gets worse during hot climate. It can be diagnosed through KOH test.

Cause

It is caused due to the Trichophyton rubrum fungus. This fungus can also result in fungal infections of the body and toe.

Symptoms

The symptoms of this disease include appearance of red, flat itchy rash on the inner side of the one or both thighs.  The rash spreads outward in a ring like circular pattern whereas the center clears up partially. The border of the rash is marked sharply, is raised slightly and at times is beefy red in color. This infection can spread to the genital and public regions and at times can affect the buttocks.

Treatment

The best treatment for this disease involves application of topical creams or ointments since the fungus affects the top layer of the skin. Most of the medications are are available only through prescription but some of the medicines can be brought OTC. These creams have to be applied twice a day for at least two weeks. In case the rash turn extremely red or itchy or if it causes blisters at the edge then in that case application of topical steroids such as hydrocortisone helps. Steroids should not be used without consulting a doctor as they can worsen the rash. The disease can be treated within a few weeks but it can reoccur. In case of chronic infection the treatment might last for one or two months.

In order to prevent this disease one should keep the body clean, should dry oneself after baths and showers, try wearing loose clothes and should not share towels or clothing and after any athletic activity should shower immediately.
