Psoriatic arthritis is a condition that causes inflammation of the joints.
This causes the joints to become painful, stiff and often swollen. Usually only people who have a skin disease called psoriasis are affected by psoriatic arthritis.
Only one or two out of every 10 people with psoriasis will develop this type of arthritis.
