Unnatural movement or locking of your thoracic vertebrae and its related tissues can restrict movement of your heart, lungs, and other organs in your chest cavity and also prevent the proper draining of fluids from your head, brain, throat, heart and lungs which may cause congestion of body fluids and affect the proper flow of blood to these organs.
Also, the vertebral subluxation complex can irritate the nerves coming from your spine to your sympathetic chain, affecting the blood supply and proper function of your internal organs.
Because unhealthy spinal function in the thoracic area can affect so many organs, when your chiropractor releases pressure in this area the benefits can be both physically and psychologically profound.
