Some people may
suffer "flare-ups" of the itchy rash in response to certain
substances or conditions. For some, coming into contact with rough or coarse
materials may cause the skin to become itchy. For others, feeling too hot or
too cold, exposure to certain household products like soap or detergent, or
coming into contact with animal dander may cause an outbreak. Upper respiratory
infections or colds may also be triggers. Stress may cause the condition to
worsen.
Although there is
no cure, most people can effectively manage their disease with medical
treatment and by avoiding irritants. The condition is not contagious and can't
be spread from person to person.
