The same fungus that causes athlete’s foot can also cause itchy, red rashes in the groin area. This condition can be very common in men who sweat a lot.
Doctors recommend over-the-counter antifungal treatments such as Lamisil AT. While most infections respond well to these treatments, if you find that your skin isn’t healing after a week, talk to your doctor.
Reduce your rash risk by:
Keeping your groin area dry
Changing your underwear daily
Making sure that whatever you wear down there is clean and fits correctly
