Thoracic Outlet Syndrome: Overview
Thoracic Outlet Syndrome (TOS) is a nerve compression syndrome affecting the ulnar nerve of the arm. Sometimes the blood vessels are also compressed. Symptoms usually occur in the hands and fingers, including hand pain, finger pain, paresthesias (tingling sensations, burning sensations, numbness), and similar symptoms. Finger tingling and paresthesias may affect only the smallest two fingers (ring finger and pinky finger), or may affect the whole hand.
