The cavity that exists between your first rib and your clavicle is filled with nerves, veins, and muscle. When any of them become compressed, a condition called thoracic outlet syndrome (TOS) can develop. Once diagnosed, doctors can recommend physical therapy or measures that can help relieve the discomfort. If the affliction is severe or the initial rehabilitation measures are ineffective, surgery may be recommended as the next step.

This article will provide an overview of thoracic outlet syndrome. We'll describe the symptoms that patients may notice as the condition advances. We'll also explore the different forms of the affliction and its potential causes. Finally, we'll explain how doctors diagnose the disorder. Remember is you experience or see any of the symptoms describe here it is advised that you seek professional medical attention as soon as possible. Annual medical check-ups are necessary for your overall health diagnosis and well being.

Types, Symptoms, And Possible Causes

There are three variations of the condition, including neurogenic, vascular, and nonspecific-type. It's worth noting that many professionals within the medical community question whether nonspecific-type thoracic outlet syndrome truly exists.

Neurogenic TOS accounts for a large majority of cases. This subtype affects the brachial plexus and compresses the spinal nerves. As a result, you might feel a tingling or aching sensation in your fingers. You may also notice a persistent pain between your shoulder and the base of your neck.

Vascular TOS occurs when the arteries or veins that run underneath your collarbone are compressed. When this happens, you might notice your hands turning blue as the blood flow becomes restricted. Blood clots can also develop, leading to a painful swelling in your arms.

Nonspecific-type TOS is harder to pinpoint (which is one of the reasons why doctors are often hesitant to diagnose it). Patients will complain of a persistent pain within the thoracic cavity, but the cause cannot be identified.

All forms of TOS are the result of compression and can manifest from the same causes. For example, some patients are born with congenital defects. Others may be involved in an event which can cause trauma to the affected area (i.e. traffic collision). Still others may suffer from long-term posture problems. Each of these can compress the veins, blood vessels, and nerves under the collarbone.

Diagnosing The Issue

Because thoracic outlet syndrome impacts each patient differently, doctors often find it hard to diagnose the condition. He or she will normally look for physical symptoms, such as a loss of color in your arms, loss of grip strength, or restricted arm mobility. Your doctor may also inquire about the type of work involved in your job since TOS is often linked to repetitive activities. He or she may also attempt to trigger the symptoms by using a series of provocation tests.

Thoracic outlet syndrome is a disorder with symptoms that becomes more severe with time. If you observe any of the warning signs described above, make an appointment with your doctor.
