Psoriatic Arthritis

Psoriatic arthritis (PsA) is a chronic inflammatory autoimmune condition characterized by inflamed joints. Psoriatic arthritis often, but not always, occurs in people who also have psoriasis, an autoimmune skin condition that results in scaly, red itchy patches. PsA can affect the large joints such as the knees and shoulders but also may also occur in joints like the fingers, toes, back or pelvis. Symptoms usually start between ages 30 and 50 and can lead to mild symptoms or chronic inflammation that may result in joint damage if not treated appropriately. Men and women are equally at risk.
