More commonly referred to as TOS, thoracic outlet syndrome is a condition caused by compression of the superior thoracic outlet. There is a neurovascular bundle (nerves and blood vessels) that runs from the base of the neck through the top of the shoulder, and down into the arms.

These nerves and blood vessels run directly between the Anterior/Middle Scalene muscles and the first rib. When these muscles are over used, and become irritated they put pressure on the nerovascular bundle causing a variety of symptoms running down the arm, and even into the fingers.

Symptoms of TOS

  • Neck & shoulder pain

  • Arm pain

  • Numbness in the arm, hand or fingers

  • Impaired circulation to the extremities

  • Weakness in the shoulders

  • Weakness in the arms & hands

Tips to Help With Thoracic Outlet Syndrome

Most of us will experience TOS symptoms at some point in our lives. The Scalene muscles are used as accessory breathing muscles and are often overused due to the forward drawn postures. TOS is not immediately life threatening but can be a precursor to frozen shoulder, or carpel tunnel syndrome, so it is important to get check out if you are experiencing these symptoms.

The most common surgical procedure is to remove the first rib, which ends up being a nasty surgery and pretty painful. The team at Northern Edge Chiropractic LLC in Plymouth, MN gets great results treating TOS. By adjusting the first rib and doing muscle therapy on the Scalene’s we can reduce the amount of irritation on the nerves and blood vessels running through the superior thoracic outlet.
