Doctor's Notes on Jock Itch
Jock itch is the name that refers to an itchy rash in the groin that commonly involves the inner thighs and adjacent skin, including the scrotum, in males. The most common cause of jock itch is friction, humidity, and heat. However, fungal and bacterial infections may also be present in some cases. Jock itch can occur in both men and women, but it is more common in men than in women because of the friction and humidity associated with the male genital area.
Symptoms of jock itch begin in areas of skin folds, where the skin rubs against neighboring skin. Signs and symptoms associated with jock itch include
- skin redness,
- a raised red rash with sharp borders, and
- pimples that may occur at the edge of the rash.
The irritation of the rash increases over time and can in some cases lead to breakdown of the skin.
What Is the Treatment for Jock Itch?
Jock itch can be treated by antifungal medications that are available over the counter. These may be creams, lotions, or sprays. It is important to use the medication for as long as the directions indicate. Keeping the affected area clean and dry can also help healing. You should use a different towel to dry the affected area. It can also help to avoid tight-fitting clothes or undergarments.
