Thoracic outlet syndrome (TOS) can cause pain, numbness, and weakness in the shoulders, neck, and arms when nerves or blood vessels become compressed in the thoracic outlet area.
Stretching and strengthening exercises are often recommended to help relieve pressure in the shoulders and chest while improving posture and mobility. When combined with massage therapy, these exercises can help reduce tension and restore healthy movement.
How Thoracic Outlet Syndrome Is Diagnosed
Diagnosing thoracic outlet syndrome can be challenging because symptoms vary widely from person to person.
To diagnose the condition, a doctor will typically review your symptoms, medical history, and perform a physical examination. In some cases, additional tests may be recommended to rule out other conditions with similar symptoms.
Provocation Tests
Doctors may use provocation tests to reproduce symptoms and determine whether thoracic outlet syndrome is present.
During these tests, a doctor may ask you to move your arms, neck, or shoulders into certain positions while monitoring symptoms such as numbness, tingling, or pain.
One commonly used evaluation is the Roos Test, which involves holding the arms in an elevated position while repeatedly opening and closing the hands to see whether symptoms appear.
Conservative Treatment Options
In many cases, thoracic outlet syndrome can be treated effectively with conservative care, particularly when the condition is identified early.
Treatment may include:
- Massage therapy
- Physical therapy
- Postural correction
- Stretching and strengthening exercises
These exercises help strengthen the muscles around the shoulders and improve posture, which can open the thoracic outlet and relieve pressure on nerves and blood vessels.
When done consistently and combined with regular massage therapy, these treatments may reduce muscle tension and improve range of motion.
Medications for Certain Cases
If thoracic outlet syndrome involves blood clots in the veins or arteries, a doctor may prescribe clot-dissolving medications called thrombolytics.
After treatment, medications that help prevent blood clots, known as anticoagulants, may also be recommended.
Surgical Options
In some situations, surgery may be recommended if conservative treatments are not successful or if symptoms continue to worsen.
Thoracic outlet surgery carries potential risks, including injury to the brachial plexus nerves, and symptoms may sometimes return after surgery.
For arterial thoracic outlet syndrome, surgeons may need to repair or replace a damaged artery using a graft from another part of the body or an artificial graft.
Rehabilitation and Home Exercises
If you are diagnosed with thoracic outlet syndrome, a doctor or physical therapist may recommend exercises to strengthen and support the muscles surrounding the thoracic outlet.
To help reduce stress on the shoulders and surrounding muscles:
- Maintain good posture
- Take frequent breaks from repetitive activities
- Maintain a healthy weight
- Avoid carrying heavy shoulder bags
- Modify activities that worsen symptoms
- Create a workspace that supports proper posture
What You Can Do in the Meantime
While waiting for a medical appointment, some people may experience temporary relief by taking nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen.
Symptoms may also improve by maintaining proper posture and avoiding repetitive movements or heavy lifting.
Massage Therapy for Thoracic Outlet Syndrome
Massage therapy may help reduce muscle tension and improve mobility in the shoulders, neck, and chest.
Focused massage, stretching, and physical therapy techniques can help relieve discomfort associated with muscle tightness and weakness around the thoracic outlet.
Some sessions may also incorporate therapies such as TENS stimulation to support deeper muscle relaxation.
