Psoriatic arthritis is a type of arthritic inflammation that causes pain, stiffness and swelling in and around the joints, as well as sites of tendon and ligament connection to bone. Symptoms vary according to location and activity over time. Approximately 1 in 20 patients with psoriasis will develop arthritis with the skin condition. In most cases, psoriasis precedes the development of arthritis.
