Thoracic Outlet Syndrome (TOS) is a condition that often goes undiagnosed or misdiagnosed because its symptoms can mimic other common hand and arm conditions. If you’ve been experiencing unexplained pain, numbness, or weakness in your arm or hand, it’s essential to consider whether TOS might be the culprit. In this article, we’ll explore the causes of TOS, its symptoms, how to differentiate it from other conditions, and what you can do if you suspect you have it.
What Is Thoracic Outlet Syndrome?
Thoracic Outlet Syndrome occurs when the nerves and blood vessels that pass through the thoracic outlet—the space between your collarbone and first rib—become compressed. This compression can lead to a variety of symptoms affecting the arms and hands.
TOS is typically categorized into three types:
Nerve Compression TOS – The most common type, affecting the brachial plexus nerves. The brachial plexus is a combination of nerves that come from the neck and give movement and sensation to the arm.
Vein Compression TOS – Caused by compression of the veins, leading to swelling and discoloration.
Artery Compression TOS – The rarest form, resulting from compression of the arteries, potentially causing cold and pale fingers.
Symptoms of Thoracic Outlet Syndrome
The symptoms of TOS can vary depending on which structures are compressed. Common symptoms include:
Pain in the neck, shoulder, or arm
Numbness or tingling in the fingers
Weakness in the hand or grip
Swelling or discoloration in the arm or hand
A feeling of heaviness in the arm, especially after overhead activities
How to Do I Know it's TOS and Not Something Else?
Many conditions can cause similar symptoms to TOS, making an accurate diagnosis crucial. Here’s how TOS compares to some other common conditions:
Carpal Tunnel Syndrome (CTS): While CTS primarily causes numbness, tingling, and pain in the thumb, index, and middle fingers, TOS symptoms often extend up the arm and involve the entire hand. CTS also typically worsens at night, whereas TOS symptoms often flare with overhead movements.
Cervical Radicular Pain: This condition occurs when a nerve in the neck becomes compressed, leading to radiating pain, weakness, or numbness down the arm. Unlike TOS, cervical radiculopathy symptoms often worsen with neck movements rather than shoulder or arm positioning.
Tendonitis or Overuse Injuries: Conditions such as tennis elbow or rotator cuff tendinitis usually present with localized pain and are activity-dependent, whereas TOS symptoms are often triggered by specific postures or prolonged arm positioning.
How Chiropractic Care Can Help with TOS
Many people with TOS experience relief through conservative treatments such as chiropractic care
. Chiropractic adjustments, soft tissue therapy, and corrective exercises can help improve posture, relieve nerve compression, and restore proper movement patterns. Additionally, the McKenzie Directional Technique, which we specialize in, can be highly effective in addressing postural imbalances contributing to TOS symptoms.
