 The vagus nerve travels nearer to the skin are various points along the way.

 A quote from another source:
-    The incoming signals lead to many reflex responses, mediated at cell stations in the brain stem, and entailing either autonomic or somatic motor responses. For example: irritants in the airways stimulate vagal sensory nerve endings and lead to a cough reflex; information on the state of inflation of the lungs causes modification of the breathing pattern; distension of the stomach leads to reflex relaxation of its wall.

-    The outgoing, motor fibres in the vagus nerves represent most of the cranial component of the parasympathetic division of the autonomic nervous system. Vagal stimulation slows the heart beat, and excessive stimulation can stop it entirely. When Otto Loewi first showed, in 1921, that stimulation of the vagus nerve to a frog heart caused something to be released that could slow down another heart that was linked to the first only by fluid perfusion, he called the unknown factor Vagusstoff. We know now that vagal nerve endings act on the heart's pacemaker by the release of the transmitter acetylcholine; this modulation of the heart rate is continuous, counterbalancing the action of the sympathetic nerves at the same site. The vagus nerves also provide a pathway for reflex reduction of the cardiac output if the blood pressure tends to rise. In the lungs, they stimulate the smooth muscle in the wall of the bronchial tree, tending to increase the resistance to airflow (by causing bronchoconstriction), again counterbalancing the sympathetic effect which tends towards relaxation. In the alimentary tract they stimulate smooth muscle in the walls of the stomach and of the intestines, acting through the nerve networks between the layers of smooth muscle, but they have the opposite action on the smooth muscle sphincter that tends to prevent the stomach contents from moving on. They stimulate glandular secretions of stomach acid and of the digestive enzymes that are released into the stomach and intestine, and the ejection of bile from the gall bladder. They also influence the release from the pancreas of the hormones that promote the storage of absorbed nutrients. All these effects add up to support of activity in the alimentary system during and after eating, when the parasympathetic effects predominate over the opposite quietening effects of the sympathetic nerve supply.

-    The term ‘vaso-vagal’ attack refers to fainting, when — from a variety of causes ranging from emotional shock to the pain of injury — there is a strong parasympathetic outflow in the vagus nerves, causing slowing of the heart that leads to a fall in blood pressure sufficient to cause unconsciousness.

 So, you can actually stop your heart with excessive stimulation? I didn't know that!
-There were other ideas that were free and interesting, like *humming, singing, inversion, cold water*, and other body based methods.

 Different researchers have also identified that the vagus nerve controls glucose homeostasis, independent of changes in insulin (via Leptin). At least, it works that way in non-diabetics.
+The vagus nerve is a cranial nerve that runs from brainstem to abdomen and is responsible for communicating with our nervous system to turn on our bodies’ parasympathetic nervous system, or relaxation response.   When the vagus nerve is stimulated it releases the neurotransmitter acetylcholine. According to an article by Angela Savitri Petersen, “Acetylcholine is responsible for learning and memory. It is also calming and relaxing, which is used by the vagus nerve to send messages of peace and relaxation throughout your body. New research has found that acetylcholine is a major brake on inflammation in the body.”

 <blockquote>I just spent some time on youtube looking for massage of the vagus nerve and found every imaginable way of stimulating the nerve but almost nothing using massage. Some of the ways mentioned I am already doing, fasting, cold shower, exercise, and I still have weak balance and tinnitus.</blockquote>
