My Thoracic Discography - NEGATIVE

[Tbackpain1]

Aaron,

I tend to think that while there's no direct correlation between a thoracic nerve and not being able to speak, there is definitely a link between high pain levels and the Vagus Nerve. This nerve is part of your Autonomic Nervous system. When I have very very bad flares with the t-spine pain, I get a classic Vagus Nerve response (rapid heartbeat, clammy skin, etc) and I have passed out a few times as well.

The vagus nerve is either one of two cranial nerves which are extremely long, extending from the brain stem all the way to the viscera. The vagus nerves carry a wide assortment of signals to and from the brain, and they are responsible for a number of instinctive responses in the body. You may also hear the vagus nerve called Cranial Nerve X, as it is the 10th cranial nerve, or the Wandering Nerve. A great deal of research has been carried out on the vagus nerve, as it is a rather fascinating cranial nerve.

Vagus is Latin for “wandering,” and it is an accurate description of this nerve, which emerges at the back of the skull and meanders in a leisurely way through the abdomen, with a number of branching nerves coming into contact with the heart, lungs, voicebox, stomach, and ears, among other body parts. The vagus nerve carries incoming information from the nervous system to the brain, providing information about what the body is doing, and it also transmits outgoing information which governs a range of reflex responses.

When the vagus nerve is stimulated, the response is often a reduction in heart-rate or breathing. In some cases, excessive stimulation can cause someone to have what is known as a vaso-vagal response, appearing to fall into a faint or coma because his or her heart rate and blood pressure drop so much. Selective stimulation of this nerve is also used in some medical treatment; vagus stimulation appears to benefit people who suffer from depression, for example, and it is also sometimes used to treat epilepsy.
