What is psoriatic arthritis?

In this video we will describe what happens to your joints in psoriatic arthritis, its association with psoriasis, what is the immune system and what the symptoms of PsA are. Psoriatic arthritis (PsA) is an autoimmune disease - a form of inflammatory arthritis that can cause pain, swelling and sometimes damage to any joint in the body. It is a rarer form of arthritis compared to other forms of the disease (Osteoarthritis and Rheumatoid Arthritis). About 1 in 50 people have psoriasis and up to one-third of them may develop PsA (note that prevalence rates and figures vary considerably), so having psoriasis does not automatically mean you will have PsA. In fact, most people with psoriasis never develop it. Although PsA generally occurs after psoriasis develops there are cases where the arthritis develops first. PsA usually begins slowly spreading to other joints over a period of a few weeks or even months. In rare instances PsA can develop quickly and can be quite severe. It is an unusual arthritis because it can look very different from person to person.
