When to speak to a doctor
Go to the emergency room or call 911 for widespread redness covering most of the body with fever or chills, or for widespread small pus-filled bumps — erythrodermic and pustular psoriasis are medical emergencies. See your doctor for new joint pain, swelling or morning stiffness, which may indicate psoriatic arthritis and benefits from early treatment.
