What should you know about neurogenic thoracic outlet syndrome?

The nerves that travel from the neck into the arm pass through a narrow area between the neck muscles, first rib, and collarbone. Changes in posture, repetitive overhead activity, muscle tightness, or an injury can irritate this pathway. Symptoms may include arm numbness and tingling, aching around the neck or shoulder, hand weakness, or discomfort that increases when the arm is raised. These symptoms overlap with neck nerve irritation and other upper-limb problems, so an examination matters.

A clinician may assess neck and shoulder movement, sensation, strength, and how symptoms change with arm position. Treatment commonly starts with activity adjustment and a tailored rehabilitation plan. Physiotherapy may address breathing mechanics, shoulder-blade control, chest flexibility, and gradual strengthening; [Physiotherapy](/treatments/physiotherapy-and-rehabilitation/physiotherapy/) can be part of that plan. [Postural Correction Therapy](/treatments/physiotherapy-and-rehabilitation/postural-correction-therapy/) may help when prolonged slouching or forward-head posture contributes. Avoid repeatedly provoking symptoms while keeping the arm gently mobile.

Arrange an assessment if numbness keeps returning, grip feels weaker, pain limits sleep or work, or symptoms continue after changing the provoking activity. Seek urgent care for sudden or persistent arm weakness, a cold or blue hand, marked swelling, severe chest or neck pain, or symptoms suggesting a stroke such as facial drooping or speech difficulty. A new [Hand Numbness](/symptoms/hand-numbness/) symptom deserves attention when it is progressive or affects daily tasks.

Which movements or positions are reproducing my symptoms? Could the problem be coming from my neck, shoulder, or wrist instead? What exercises are appropriate now, and which should I pause? How will we track strength, sensation, and functional progress?
