Psoriatic arthritis is a type of inflammatory arthritis that can develop in people who have psoriasis, a chronic autoimmune skin condition that causes rapid skin cell growth and renewal. Psoriatic arthritis differs from other forms of arthritis because it involves the skin and it affects the joints differently.
Areas of the Body Affected by Psoriatic Arthritis
The joint pain, swelling, and stiffness associated with psoriatic arthritis can affect any joint including the elbows, neck, back, shoulders, wrists, and fingers, but it most commonly occurs in large joints of lower extremities such as the knees, feet, and ankles.
In addition, the skin effects of psoriatic arthritis including red patches of skin with silvery scales (plaques), commonly occur on the elbows, scalp, knees, and around the ears.
