Psoriatic Arthritis causes pain and swelling in some joints and scaly skin patches on some areas of the body. It is related to the skin condition psoriasis.

About 95% of those with psoriatic arthritis have swelling in joints outside the spine, and more than 80% of people with psoriatic arthritis have nail lesions. The course of psoriatic arthritis varies, with most doing reasonably well.

Symptoms include:

• Silver or grey scaly spots on the scalp, elbows, knees and/or lower end of the spine.
• Pitting of fingernails/toenails.
• Pain and swelling in one or more joints
• Swelling of fingers/toes that gives them a "sausage" appearance.
