Psoriatic arthritis (PsA) happens when a body’s immune system becomes overactive and attacks normal tissues within the body. Patients with PsA can experience swelling, stiffness and pain in their joints and surrounding tissues, as well as nail changes and extreme fatigue.
According to the National Psoriasis Foundation (NPF), up to 30 percent of people with psoriasis will develop psoriatic arthritis.
PsA, which is an inflammatory form of arthritis, affects an estimated 2.25 million Americans.*
People with psoriatic arthritis experience the red patches of skin and silvery scales that psoriasis patients experience, as well as joint pain and stiffness associated with autoimmune forms of arthritis.
PsA can affect any part of the body, including fingertips and spine, and the severity of the disease can range from mild to severe. For patients with psoriatic arthritis, disease flare ups are relatively unpredictable as they often alternate with periods of remission.
There is currently no cure for psoriatic arthritis.
Onset of psoriatic arthritis is different for every patient. In some people it develops slowly with minimal symptoms; but, in others it develops quickly and painfully.
Common symptoms include:
Lower back, wrists, knees or ankle could also show signs and symptoms. In 85 percent of patients, psoriasis occurs before joint disease.
