Intertrigo is a common rash found in the folds of the skin. Common areas of involvement include the groin, in the folds of the abdomen, and under the breasts. Because of the friction, warmth, and moisture in the skin folds, the affected areas become red and raw. Symptoms can also include itching and burning. The affected areas can be predisposed to secondary infection with yeast, fungus, or bacteria. Intertrigo can be caused by or aggravated by heat and humidity. Treatment involves trying to keep the area clean and dry, applying barrier creams, and using topical medications to treat the inflammation and any possible infection.
