Thoracic Outlet Syndrome (TOS) and Pain Relief: Understanding the Causes and Treatment Options

Thoracic outlet syndrome (TOS) is a condition that can cause pain, numbness, and tingling in the arms and hands. It is caused by compression of the nerves and blood vessels in the thoracic outlet, which is the space between the collarbone and the first rib.

Common Causes of TOS

There are several factors that can contribute to TOS, including:

  • Tight pectoral muscles (pecs): The pecs are the muscles that make up the chest. When they are tight, they can put pressure on the nerves and blood vessels in the thoracic outlet.

  • First rib abnormalities: The first rib is a bone that runs from the front of the chest to the spine. In some people, the first rib may be abnormally shaped or positioned, which can compress the nerves and blood vessels in the thoracic outlet.

  • Scalene muscle tightness: The scalene muscles are a group of muscles that run from the neck to the ribs. When they are tight, they can pull on the nerves and blood vessels in the thoracic outlet.

Symptoms of TOS

The most common symptoms of TOS include:

  • Numbness, tingling, and pain in the arms and hands: These symptoms are often worse when the arms are raised overhead or held in the same position for a long period of time.

  • Weakness in the hands: This weakness can make it difficult to grip objects or perform fine motor tasks.

  • Fatigue in the arms: This fatigue can make it difficult to perform everyday tasks, such as carrying groceries or typing.

Treating TOS

Treatment for TOS typically involves a combination of conservative measures, such as:

  • Physical therapy (Obviously DUHHHH): Physical therapists like myself can teach you exercises to stretch and strengthen the muscles around the thoracic outlet. They can also provide manual therapy techniques to help relieve pain and improve range of motion.

  • Posture education: Maintaining good posture can help to reduce pressure on the nerves and blood vessels in the thoracic outlet.

  • Activity modification: Avoiding activities that aggravate your symptoms, such as overhead lifting or reaching, can help to prevent further injury.
