Thoracic Outlet Syndrome (TOS) is a condition that involves the compression of nerves, arteries, or veins in the thoracic outlet, the passageway from the lower neck to the armpit. This syndrome can cause various symptoms, including pain, weakness, numbness, tingling, and sometimes a general feeling of discomfort in the upper body. TOS affects the upper limbs, hands, armpits, upper back, neck, and pectoral area.
There are three main types of Thoracic Outlet Syndrome: neurogenic, venous, and arterial. The neurogenic type, which is the most common, involves the compression of nerves. Symptoms of TOS can be similar to other conditions, such as cervical radiculopathy or a pinched nerve. Cervical radiculopathy often occurs when a nerve in the neck is compressed or irritated, leading to pain that may radiate into the shoulder, arm, or hand.
Symptoms of Thoracic Outlet Syndrome may include pain or aches in the neck, back of the head, or shoulder, tingling or numbness in the fingers, hand, or arm, and increased discomfort or weakness when raising the arm for extended periods. Treatments for TOS may involve physical therapy, exercises, and in severe cases, surgery.
Understanding the differences between TOS and other similar conditions, such as pinched nerves or cervical radiculopathy, is crucial for proper diagnosis and treatment. For more detailed information about Thoracic Outlet Syndrome and related conditions, visit the Hospital for Special Surgery, the Harvard Health page on neck pain, and the Ohio State Medical Center resources on pinched nerves.
Thoracic Outlet Syndrome is often mistaken for other conditions due to overlapping symptoms. It is essential to consult healthcare professionals for an accurate diagnosis and appropriate treatment plan.
