Psoriatic arthritis

Psoriatic arthritis is a type of arthritis linked with psoriasis, a chronic skin and nail disease. Psoriasis causes red, scaly rashes and thick, pitted fingernails. Psoriatic arthritis is similar to rheumatoid arthritis (RA) in symptoms and joint swelling (inflammation). But it tends to affect fewer joints than RA.
