What is Psoriatic Arthritis?

Psoriatic Arthritis (PsA) is a type of chronic inflammatory arthritis that affects some people who have psoriasis, the condition associated with patches of red, itchy, flaky patches called scales, usually found on the knees and elbows, and thick, pitted fingernails.  Most patients develop psoriasis first and are later diagnosed with PsA although the joint pain can begin before the psoriasis symptoms appear. Both conditions are believed to be caused by your immune system and the connection between the two can be easily missed! The National Psoriasis Foundation estimates that up to 30% of people with psoriasis also have psoriatic arthritis, and it most commonly strikes between the ages of 30 and 50. There is no cure for PsA but there is treatment to ease symptoms and prevent bone loss and disabling joint damage.
