7 Common Symptoms of Psoriatic Arthritis

2. Swollen Finger or Toes

Swollen fingers or toes, known as dactylitis, are another common symptom of psoriatic arthritis. This sausage-like swelling—which affects approximately 40 percent of people with the condition—occurs along the entire length of the finger or toe, and is caused by inflammation of the tendons.

This helps to distinguish it from other forms of arthritis, where swelling is often confined to the area surrounding a single joint. According to Health.com, this symptom may appear even before the person experiences any joint issues.
