MONDAY, Aug. 25 (HealthDay News) -- Psoriasis can be a maddening disease.
Patches of thick, inflamed skin covered with silvery scales form here and there on the patient's body, often on the elbows, knees, other parts of the legs, scalp, lower back, face, palms, and soles of the feet. They usually itch or feel sore, and the more of the patches there are, generally, the worse the person suffers.
