Intertrigo occurs when two skin surfaces chafe against each other. It can appear anywhere on the body but is frequently found on the inner thighs, armpits, and groin; the crease on the back of the neck; the bottom of breasts; and below the belly. Bacterial, fungal, or yeast infections may cause intertrigo. Symptoms generally include a raw, reddish-brown rash that itches and oozes. The skin may crack or bleed in more severe cases.
Treatment for intertrigo focuses on keeping the affected area dry and exposed to air. Your dermatologist may prescribe steroidal creams, oral antibiotics or antifungal medications (depending on the cause of the infection) to relieve itching and promote healing. Applying warm, moist compresses to the area can also help relieve itching.
