What is the first treatment for thoracic outlet syndrome?

Thoracic outlet syndrome involves pressure or irritation affecting nerves or blood vessels as they pass between the neck, shoulder and upper chest. Symptoms can include arm pain, tingling, heaviness or colour and temperature changes. The treatment plan depends on which structures are involved, so diagnosis matters before exercises begin.

Physiotherapy may work on neck and upper-back alignment, shoulder-blade control, chest mobility and breathing mechanics. The intention is to reduce repeated compression and improve how the arm is supported during daily activity.

Avoid carrying heavy loads on the affected side and limit positions that reproduce tingling or heaviness, especially prolonged overhead work. Change positions regularly and keep movements gentle. A physiotherapist can build a staged program through [Physiotherapy](/treatments/physiotherapy-and-rehabilitation/physiotherapy/) and may use [Postural Correction Therapy](/treatments/physiotherapy-and-rehabilitation/postural-correction-therapy/) to address contributing alignment and movement habits.

Do not force stretches that increase nerve symptoms or make the hand change colour. Your clinician may need to distinguish nerve-related symptoms from vascular symptoms before recommending a home program.

Seek urgent medical care for sudden arm swelling, a pale or blue hand, unusual coldness, severe new weakness or chest pain. Arrange an assessment for persistent tingling, dropping objects, worsening arm fatigue or symptoms that reliably appear with overhead activity. These features need examination rather than self-treatment alone.

Do my symptoms suggest nerve, artery or vein involvement? Which positions should I avoid? What exercises are safe, and what changes should prompt urgent review?
