Thoracic Outlet Syndrome

WHAT YOU SHOULD KNOW:

Thoracic outlet syndrome (TOS) occurs when nerves or blood vessels are pinched in the thoracic outlet. The thoracic outlet is the area between your collarbone and your first rib. Nerves and blood vessels run through the thoracic outlet as they go from your chest out to your hands.


INSTRUCTIONS:

Physical therapy:

A physical therapist teaches you exercises to strengthen the muscles in your neck, shoulders, and back. This can help increase the amount of room in the thoracic outlet. These exercises can also help improve your posture and decrease pain.

Self-care:

  • Practice correct posture.

  • Do not sleep with your arms above your chest.

  • Avoid activities that involve repeated movements.

  • Do exercises as directed to strengthen and stretch your shoulder and neck muscles.

Medicines:

You may need any of the following:

  • Nonsteroidal anti-inflammatory (NSAID) medicine may decrease swelling or pain. This medicine can be bought with or without a doctor's order. NSAIDs can cause stomach bleeding or kidney problems in certain people. If you take blood thinner medicine, always ask your primary healthcare provider (PHP) if NSAIDs are safe for you. Always read the medicine label and follow the directions on it before using this medicine.

  • Muscle relaxers or other medicines to decrease nerve pain may be needed. Ask your PHP for more information about these medicines.

  • Prescription pain medicine may be given to decrease pain. Do not wait until the pain is severe before you take this medicine.

  • Take your medicine as directed. Contact your PHP if you think your medicine is not helping or you have side effects. Tell him if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.

Follow up with your PHP in 3 to 4 weeks:

Your PHP may refer you to an orthopedic, neurologic, or other specialist. Write down your questions so you remember to ask them during your visits.

Contact your PHP if:

  • You have new pain, numbness, or tingling in your neck, shoulder, arm, or hand.

  • You have a weak grip that is new for you.

  • One hand looks smaller than the other.

  • You have questions or concerns about your condition or care.

Return to the emergency department if:

  • You have severe pain.

  • Your arm or hand aches or feels heavy.

  • Your arm or hand feels cold, or looks pale or blue.
