Yes. The nerves that travel from the neck into the arm control sensation and movement. If one of those nerves becomes compressed or irritated, it can cause pain, numbness, tingling, or weakness in the shoulder, arm, or hand.

Thoracic outlet syndrome occurs when nerves or blood vessels are compressed in a narrow space between the neck and shoulder. This pressure can lead to arm pain, numbness, heaviness, or weakness — especially when the arm is lifted.

Raising the arm can temporarily narrow the space around the nerves near the shoulder. If those nerves are already compressed, lifting the arm may worsen the pressure and cause numbness or tingling.

Pain in this area can come from muscles, joints, discs, or nerves. One of the most important parts of evaluation is determining which structure is actually causing the symptoms.

Surgery is usually considered after conservative treatments such as therapy, medications, or injections have not provided relief and a specific nerve compression has been identified.
