Which condition involves pressure on blood vessels and nerves near the shoulder and collarbone, causing neck and shoulder pain and numbness in the fingers with a weak grip?

Which condition involves pressure on blood vessels and nerves near the shoulder and collarbone, causing neck and shoulder pain and numbness in the fingers with a weak grip?

• A. Medial epicondylitis
• B. Ganglion
• C. Thoracic outlet syndrome
• D. Stenosing tenosynovitis

Answer: (C)

Thoracic outlet syndrome involves compression of the neurovascular bundle as it passes through the space between the collarbone and the first rib. When nerves in this area (the brachial plexus) are pressed, you get symptoms like neck and shoulder pain along with numbness, tingling, or weakness in the fingers, which can lead to a weak grip. This combination—pain in the shoulder/neck region with numbness and reduced hand strength—fits the classic pattern of compression at the thoracic outlet. The other conditions don’t match these symptoms. Medial epicondylitis is tendon overuse at the inner elbow and causes pain there, not neck or shoulder pain with finger numbness. A ganglion is a cyst near a joint or tendon that may cause a lump or local pressure but not compression of the nerves and vessels near the shoulder. Stenosing tenosynovitis is inflammation and narrowing of the tendon sheath, most often affecting finger movement (trigger finger), rather than causing neck/shoulder pain and numbness in the fingers from nerve compression.
