Thoracic Outlet Syndrome

Thoracic Outlet Syndrome Treatment

Relieve Nerve and Vascular Compression Naturally with Expert Care

Thoracic Outlet Syndrome (TOS) is a condition involving the compression of nerves or blood vessels between the collarbone and the first rib—known as the thoracic outlet. This can lead to pain, numbness, weakness, and circulation issues in the neck, shoulder, arm, and hand. At Kaizo Health, we provide non-invasive, evidence-based treatments to restore proper function, relieve discomfort, and help you return to your daily activities with confidence.

What Is Thoracic Outlet Syndrome?

TOS occurs when the space between the collarbone and the first rib becomes narrowed, compressing nerves (neurogenic TOS), blood vessels (venous or arterial TOS), or both. The condition often stems from poor posture, muscle imbalances, trauma, repetitive movements, or anatomical abnormalities.

Symptoms of Thoracic Outlet Syndrome

TOS symptoms can vary depending on the type (neurogenic, venous, or arterial), but common signs include:

• Pain or aching in the shoulder, neck, arm, or hand
• Numbness or tingling in the arm or fingers
• Weakness or fatigue in the upper limb
• Discoloration, swelling, or coldness in the arm or hand
• A feeling of heaviness in the arm, especially with overhead activity
• Reduced grip strength

Causes and Risk Factors

• Poor posture or forward head/shoulder positioning
• Repetitive overhead motions (common in athletes or manual laborers)
• Trauma (e.g., whiplash, collarbone fracture)
• Congenital abnormalities (e.g., cervical rib)
• Muscle tightness or imbalance (especially in the scalene or pectoral muscles)
• Weightlifting without proper form or recovery
