Symptoms of Psoriatic Arthritis
Suffers may suffer from psoriasis prior to developing psoriatic arthritis. This is not always the case, however. In rare instances, suffers may have limited or no noticeable signs of psoriasis on the skin.
All joints in the body can be affected by psoriatic arthritis. It does, however, most often affect the hands, feet, knees, spine, neck, and elbows. Psoriatic arthritis occurs due to it being an autoimmune condition. This means, the immune system becomes confused when protecting the body against illnesses and infections. Rather than protect the body, it attacks healthy parts thus resulting in psoriatic arthritis.
The condition occurs in a variety of people regardless of age. It is believed around 20% of people will develop psoriatic arthritis.
