Occasionally, psoriasis can manifest as red and tender skin with many small bumps that contain non-infectious pus. These bumps or pustules give this form its name: pustular psoriasis. These pustules usually remain localized to the hands and feet, but can spread in large patches anywhere on the body. As the pustules dry out, they may leave behind large sections of smooth, shiny skin. Some individuals experience nausea, fever, and chills in combination with these skin growths. Doctors have yet to discover why these pustules develop, though they have identified triggers, which include infections, emotional stress, pregnancy, and irritating topical agents.
