Psoriatic Arthritis

Back

Psoriatic arthritis is a form of arthritis that affects some people who have psoriasis — a condition that features red patches of skin topped with silvery scales. Most people develop psoriasis first and are later diagnosed with psoriatic arthritis, but the joint problems can sometimes begin before skin lesions appear.

SYMPTOMS

Pain areas: in the joints or back
Joints: stiffness or swelling
Also common: skin rash, fatigue, inflamed fingers or toes, itching, physical deformity, small dents in nails, or tendinitis

CAUSES

Lower back pain. Some people develop a condition called spondylitis as a result of psoriatic arthritis. Spondylitis mainly causes inflammation of the joints between the vertebrae of your spine and in the joints between your spine and pelvis (sacroiliitis).
