Psoriasis

Psoriasis is a long-term (chronic) scaling disease of the skin, which affects 2% – 3% of the UK population. It appears as red, raised scaly patches known as plaques. Any part of the skin surface may be involved, but the plaques most commonly appear on the elbows, knees and scalp. It can be itchy, but is not usually painful. Nail changes are present in 50% of people and 10% to 20% of people will develop psoriatic arthritis
