Thoracic outlet syndrome symptoms
There are multiple types of thoracic outlet syndrome between which symptoms vary. Neurogenic thoracic outlet syndrome is caused by compression of the brachial plexus, a network of nerves that control muscle movements and sensation in the shoulder. Most cases of thoracic outlet syndrome are neurogenic, but some are vascular or non-specific.
Vascular thoracic outlet syndrome occurs when one or more of the veins or arteries located under the clavicle are compressed, while non-specific thoracic outlet syndrome is characterized by unidentifiable chronic pain in the thoracic outlet.
Signs and symptoms of neurogenic thoracic outlet syndrome include muscle wasting in the thumb, numbness or tingling in the arms or fingers, aches and pains in the neck, shoulder, or hand, and a weakened grip. Symptoms of vascular thoracic outlet syndrome include discoloration or lack of coloration in the hand, weakness of the arm or neck, arm pain and swelling, cold fingers, and weak or no pulse in the arm.
The most common symptoms of thoracic outlet syndrome include:
- Numbness or tingling in the arms or fingers
- Pain in the neck, shoulder, or arm
- Bluish color or lack of color in the hand
- Weakness in the arm, neck, or hand
