What is Psoriatic Arthritis
Psoriatic arthritis is a form of arthritis that results from a person suffering from a skin condition known as psoriasis, which is a chronic skin disease characterised by red and scaly skin rash that occur commonly on the scalp, knees and elbows. Similar to rheumatoid arthritis, psoriatic arthritis is an autoimmune disease whereby the immune system attacks its own cells. Research shows that about one-third of the patients suffering from psoriasis will develop psoriatic arthritis.
