What is dactylitis?

ANSWER

You might hear it called sausage digits. This is often the first symptom of psoriatic arthritis. It causes your fingers and toes to swell until they look like sausages. Less than half of people with psoriatic arthritis get this condition, though it usually goes along with more severe forms of the disease.
