Nearly all uncomplicated rashes tend to go away with a basic combination of mild skin care and trying to fend off bothersome substances that worsen the situation.
Do not try to scrub the redness away. Instead of using your regular soap to wash, use a soft un-scented cleanser if the area needs cleansing, however these must be used as sparingly as possible. While using water take care not to use hot water, use warm water and pat dry the skin with a tissue rather than a towel, which may prove to be harsh to the affected area. While bathing use lukewarm water and use a non-perfumed moisturizer post bath to soften the skin. Excessive drying can also cause the skin to dry up and exacerbate the infection.
Calamine medicated lotion applied overnight on the red patch of skin will ease the discomfort and soothe any inflammation if present. Try to stay out of the heat and cover the patch with a cool cotton cloth or wear comfortable loose clothing, if you have to stay outdoors for a long period of time. At best it would be advisable not to indulge in activity that induces perspiration as that can be a factor of further irritation.
