Thoracic Outlet Syndrome

Thoracic outlet syndrome (TOS) can cause significant discomfort and limitations in daily activities due to compression of nerves and blood vessels in the cervical-thoracic outlet region. At our chiropractic clinic in Newmarket, we specialize in providing effective solutions for thoracic outlet syndrome, tailored to address the unique needs of everyone.

Symptoms of Thoracic Outlet Syndrome

Thoracic outlet syndrome can cause a variety of symptoms depending on the structures being compressed (nerves, veins, or arteries). Common symptoms include:

  1. Pain: In the neck, shoulder, and arm, which may extend to the fingers.
  2. Numbness and Tingling: Often in the fingers, hand, or arm.
  3. Weakness: In the hand or arm, making it difficult to perform certain tasks.
  4. Swelling and Discoloration: The arm or hand may swell, and the skin can appear bluish due to venous compression.
  5. Cold Sensation: In the fingers or the hand, indicating arterial compression.
  6. Tiredness: A feeling of fatigue or heaviness in the arm and hand, particularly with activity.


  1. Anatomical Variations: Congenital abnormalities such as an extra rib (cervical rib) or an unusually tight band of fibrous tissue can compress nerves or blood vessels.
  2. Poor Posture: Chronic slouching or drooping shoulders can reduce the space in the thoracic outlet, leading to compression.
  3. Trauma: Injuries from accidents, such as car crashes or falls, can cause changes in the thoracic outlet area that lead to TOS.
  4. Repetitive Activity: Repetitive overhead motions or heavy lifting, often seen in occupations or sports, can strain and compress the thoracic outlet structures.
  5. Weightlifting: Excessive muscle development around the shoulder and neck from weightlifting can lead to compression of the thoracic outlet.
  6. Pregnancy: Hormonal changes and postural adjustments during pregnancy can sometimes contribute to TOS.

These symptoms can vary in intensity and may worsen with activities that raise the arms above the head or involve repetitive shoulder movements.
