What is thoracic outlet syndrome?

Thoracic outlet syndrome (TOS) is a condition that occurs when the nerves, arteries, or veins in the thoracic outlet are compressed. The thoracic outlet is the space between the collarbone and the first rib.

TOS can cause a variety of symptoms, including:

* Pain in the neck, shoulder, or arm

* Tingling or numbness in the fingers

* Weakness in the arm or hand

* Difficulty holding objects

* Swelling in the arm or hand

TOS can be caused by a variety of factors, including:

* Repetitive overhead motions

* Poor posture

* Injuries to the neck or shoulder

* Anatomical abnormalities

Treatment for TOS typically involves physical therapy, medication, and lifestyle changes. In some cases, surgery may be necessary.

If you are experiencing any of the symptoms of TOS, it is important to see a doctor for diagnosis and treatment.
