I have had MRIs and blood tests and  everything  has came back normal.  My blood pressure tends to run a little low, and my cholesterol is good.  Im lost to what to do next.Dan
Hi and thanks for the query, The vagus nerve as you suggest is part of the parasympathetic nervous system that slows heart rate and increase intestinal contractions and secretions. The opinion of a neurologist might be needed to confirm dizziness of vagus nerve origin. Low blood pressure or hypotension could as well result from excessive activity of the vagus nerve. I would strongly recommend the opinion of a neurologist. Kind regards
