Nummular Dermatitis is round itchy patches that can affect any part of the body, but the legs and buttocks are the most common areas. Flare-ups are associated with dry skin, so the winter season in Wyoming is particularly bad time for those who suffer with this condition. Lukewarm or cool baths/showers reduce itching and help rehydrate the skin, as long as soap is not used and moisturizers are applied to wet skin, without drying off, to seal the water in the skin which allows more effective penetration and faster healing.
