Stasis dermatitis is a rash of the lower legs which is due to poor return of blood to the heart.
Usually the inner lower leg is more involved than the outer lower leg. As some people get older the veins which carry blood from the legs back to the heart do not work as well as they use to. This causes fluid to settle in the lower legs resulting in swelling and a rash known as stasis dermatitis. Sometimes the rash breaks down into a sore resulting in a stasis ulcer. Keep your legs elevated as much as possible.
