What are the symptoms of TOS?

TOS is of many types and there can be different symptoms for every type. The most common signs are a pain in the neck, shoulder, or fingers. But sometimes doctors cannot determine whether it is TOS or not. Angina has also created pain in the chest so it might be confused with TOS.

The simple solution of making a difference in both is to start walking when you feel this pain. If you feel an increment in pain when you are walking then, it must be angina. Otherwise, it a condition of TOS. On the other hand, if you feel pain when you raise your arms in the air, then it is TOS, not angina. Mostly, the TOS affects nerves, but it can also affect arteries to some extent. As told earlier that symptoms are different for different types of TOS. So here is a brief discussion about different TOS types with the related signs.

Neurological TOS

if you have issues in the soft tissues of the lower neck area that irritates the nerves and compresses them, then you are facing neurological TOS disorder. These nerves provide the power of movement to hands and arms.

Symptoms of neurological TOS

you may experience weakness in the neck, chest, and arms. Moreover, the muscles of the hands will be affected, and you may feel pain on either side of the body.

Vascular TOS

when the veins are compressed under the collarbone, then vascular TOS occurs. You need to visit your doctor if you are having the following signs.

Symptoms of Vascular TOS

the color of your hands may change, blood clots may result in swelling of the arm, cold arms, tingling in fingers, and weakness of one or two fingers or even the entire hand. Blood clots and arm fatigue are the common signs of vascular TOS.

What causes TOS?

In the above discussion, you might say that TOS happens due to the compression of blood vessels between the collarbone and first rib that creates irritation and pain in the neck and chest. But there might be some other causes of this disorder as well, which are as follows.

  • Inherited: sometimes a TOS can occur when you get an extra rib above your first rib at the time of birth.
  • Sleep disorders: if you are not having an adequate amount of sleep every day, means that sleep hours are needed for the body, then you can be entangled into TOS.
  • Sports activity:  if you are an athlete where you must make repetitive movements with your hands and arm, then you can suffer from TOS disorder more quickly than those who do not participate in sports.
  • Obesity:  if you have gained a lot of weight, then it is possible that your joints cannot hold this weight and due to overpressure, you suffer from TOS.
  • Pregnancy: the signs of TOS may be found in women when they are in pregnancy because in this period joints become loose.
  • Trauma: if you are facing any depression or trauma like accidents, then some changes in your body are observed, which also include compression of the blood vessels.

How is it diagnosed?

If your symptoms are not diagnosed at an early stage, then your nerves can start damaging excessively. You must go to your doctor for a complete physical examination. Some tests performed to diagnose TOS are as follows:

  • Medical history and review of the symptoms to check for TOS.
  • For provoking symptoms, physical movements are evaluated.
  • Study of arteries, veins, and nerves.
  • Chest X-ray for checking the rib disorder.
  • CT Scan and MRI.

By performing the above tests, a doctor can examine the condition of the patient and then go for the proper treatment.

How it can be treated?

If TOS disorder is found at an early stage, then there are more chances of its successful treatment. The treatment depends upon the type and signs of TOS. But before starting the treatment, you need to go to your doctor for knowing the benefits and drawbacks of each treatment.
