What is jock itch?

Despite its name, this infection's not just for athletes. But if it makes you feel better to say it has to do with your athleticism, we won't tell.

What happens That same troublemaker fungus at fault for athlete's foot and ringworm finds its way to your nether regions.
 
What it looks and feels like Similar to ringworm, the red, irritated patches have distinct borders and can blister, ooze, and itch.

How to treat and prevent it Do your best to air the area out by wearing dry, loose-fitting clothing, and treat with an over-the-counter antifungal. To stay itch-free, avoid skin-to-skin contact with someone who has it and don't borrow undergarments or share towels.
