Psoriatic Arthritis Overview

Psoriatic arthritis is a chronic condition that causes joint pain, swelling, and stiffness, often in people who also have psoriasis—a skin disorder with red, scaly patches. About 30% of people with psoriasis may develop this form of arthritis.

Common Symptoms

  1. Joint pain and stiffness
  2. Swollen fingers or toes
  3. Foot or back pain
  4. Red, scaly skin (if psoriasis is present)

Risk Factors

You’re more likely to develop psoriatic arthritis if you have a family history, psoriasis (especially with nail involvement), or are between the ages of 30 and 50.

Diagnosis & Treatment

At the Rheumatology Center of New York, diagnosis involves a medical history review, physical exam, lab tests, and imaging. Treatment may include medications, joint injections, physical therapy, and lifestyle changes to manage pain and prevent joint damage.
