Thoracic Outlet Syndrome (TOS) is a condition caused by the compression of nerves, arteries, or veins in the thoracic outlet — a narrow space between the collarbone and the first rib.
This compression can lead to a variety of symptoms that range from mild discomfort to debilitating pain, making early diagnosis and treatment essential.

-
Neurogenic TOS
Caused by compression of the brachial plexus (a network of nerves). This is the most common type.
-
Venous TOS
Results from compression of the subclavian vein, leading to swelling and discoloration of the arm.
-
Arterial TOS
Caused by compression of the subclavian artery, which is the least common but potentially the most serious.
-
Numbness or tingling in the arms or fingers.
-
Stiffness or restricted movement
-
Weakness in the arm or grip.
-
Swelling, bluish discoloration, or cold sensitivity in the affected arm (venous TOS).
-
A pulsing sensation near the collarbone (arterial TOS).
Extra ribs (cervical ribs) or tight fibrous bands.
Slouching or forward head posture can exacerbate compression.
Sports or occupational activities requiring repetitive arm movements.
Injuries such as a car accident or a fall.
Chiropractic Care
for TOS?
Chiropractic care offers a non-invasive and drug-free approach to managing Thoracic Outlet Syndrome.
By addressing musculoskeletal imbalances, chiropractors can help reduce the compression in the thoracic outlet and improve overall functionality.

for TOS
Through gentle adjustments, chiropractic care can alleviate nerve and muscle compression.
Chiropractic treatments restore proper alignment and reduce restrictions in the neck, shoulders, and upper back.
Addressing postural issues can prevent the recurrence of symptoms.
Spinal and shoulder adjustments improve nerve conduction, reducing symptoms like numbness and tingling.
Chiropractic Techniques for TOS
Focus on the cervical and upper thoracic spine to improve alignment and relieve nerve pressure.
Myofascial release and trigger point therapy target tight muscles contributing to compression.
Strengthening and stretching exercises to promote proper posture and prevent future flare-ups.
Targeted techniques to reduce compression and improve blood flow.
Chiropractic care is a holistic, patient-centered approach that not only treats the symptoms of Thoracic Outlet Syndrome but also addresses its underlying causes.
With the right care plan, individuals can experience relief and regain their quality of life.





Early warning signs of TOS include tingling or numbness in the fingers, persistent pain in the neck and shoulder area, weakness in the hand, or swelling in the arm. These symptoms can gradually worsen without treatment.
Individuals with poor posture, repetitive arm movements, trauma, or anatomical abnormalities like cervical ribs are at a higher risk.
Diagnosis involves a physical exam, imaging studies like X-rays or MRIs, and tests such as nerve conduction studies to identify the compression.
Chiropractic care addresses the root cause of TOS by improving alignment, reducing compression, and promoting nerve health through non-invasive techniques. It is an effective alternative to surgery and medications.
Maintaining good posture, avoiding repetitive stress on the shoulders, and performing regular stretching and strengthening exercises can help prevent TOS.
