Achy, Swollen and Itchy: Meet Psoriatic Arthritis

NBC News—May 11, 2015

NBC News reports on the diagnosis and treatment of psoriatic arthritis, a condition in which someone with psoriasis develops inflammation in the joints, which typically occurs 10 or more years after psoriasis sets in. 
According to Susan Goodman, MD, who is a rheumatologist at Hospital for Special Surgery, psoriatic arthritis can impact quality of life, but there is treatment that can address symptoms and allow people with this condition to live fully. 

Goodman said that the inflammation process in psoriasis seems to be connected to the inflammation in the arthritis, though no one knows yet what causes it. What we do know is that, like rheumatoid arthritis (RA), psoriatic arthritis is an autoimmune disease. That means one's immune system attacks its own joints, causing inflammation, pain and swelling.
