This term is used to describe the related syndromes that are caused by the nerve compression in the upper body, especially the nerves in the arms, shoulders, chest and neck. The thoracic outlet syndrome is brought about by abnormal compression of the thoracic outlet and muscles in the cervical spine and lower axilla. This is a common reason why people have numbness and tingling down either one or both of their arms/hands. There are three different types of thoracic outlet syndrome – Arterial TOS, Venous TOS and Neurogenic TOS.
The symptoms of thoracic outlet syndrome can be very similar to the symptoms caused by Raynaud’s syndrome. The most common symptoms of thoracic outlet syndrome are paleness in the palms or fingers of one or both hands or changes in the color of the arms, such as noticing blue or red patches; weakness in the neck, arms, shoulders and hands; feeling numbness, tingling and/or “pins and needles” in the arms and hands; tenderness in the supraclavicular area. Many doctors agree that thoracic outlet syndrome is tied to compression of the brachial plexus or subclavian vessels which run down the neck to the armpits and arms. 
If you suffer from thoracic outlet syndrome, then you need to talk with your doctor before you start using some of the below mentioned home remedies so in this way you will avoid side effects.

Manage stress: It is known that the stress can worsen thoracic outlet syndrome which will increase the tension and tightness.

Omega – 3 fatty acids: It is known that Omega – 3 fatty acids can help to manage pain by reducing the inflammation, suppress the production of cytokines and enzymes which can attack your joints and improve the circulation.

Some foods rich in Omega – 3 fatty acids are flax (flaxseed oil, flour or seeds of flaxseed); eggs; soybeans; some types of seaweed (used a lot in Japanese cooking and sushi); walnuts; flaxseeds; trout; anchovies; sardines; mackerel; herring and salmon.

Fix your work setup: If you are spending a lot of time sitting at a desk working each day, then you should adjust your workstation to avoid sitting with poor posture and hunching over all day. This is very important because the poor posture can cause problems relating to the inadequate blood supply to the arms over long periods. You should use a standing desk because it can help to avoid sitting all day and it can prevent hunching over.
