Psoriatic arthritis sometimes but not exclusively affects individuals who have psoriasis, a skin disorder. Both conditions are chronic, which means they are long lasting, and both have flare-ups followed by remissions. Psoriatic arthritis tends to strike the larger joints in the body, including the legs and the joints in the patient's finger and toes. It is also a problem for the hip and back. When it affects the bones of the spine, it can be classified as a type of spondyloarthropathy. Symptoms are different for different individuals. Some patients have only mild symptoms, while symptoms are severe and potentially crippling in others. The condition usually appears in adults, though it has been known to appear in children. In some cases, the arthritis symptoms present even before the symptoms of psoriasis.
