Psoriatic arthritis is a condition that occurs in up to 8 percent of people who have psoriasis (a skin condition that is characterized by scaling and swelling). In a person with this type of arthritis, the joints (and sometimes other areas of the body) become inflamed. Joint pain and tenderness do not occur as often with this form of arthritis as they do with other types of arthritis. Treating this condition can involve lifestyle changes, medications, and routine monitoring.
