Vagus Nerve - Lightheaded

[lfreem02]

I am a 40 year old female, and have been experiencing lightheadedness for two months.  My resting heart rate also went up to 90, which used to be around 70.  I have been tachycardia at times.  I have had many tests for my heart and they came back normal.  I have had a tilt table test and was told that my vagus nerve is being over stimulated, but the cardiologist doesn't know why.  I was told that I have orthostatic hypotension, but I am not seeing the pooling in the legs, and there are times my feet fall asleep.  I have lightheadedness throughout the day without a change in position, and then have episodes where I feel a weird sensation in my stomach, tightness in my chest, and then lightheadedness (sometimes I feel like I will pass out).  I do have GERD, Barrett's Esophagus, and a hiatal hernia.  I have taking Pindolol since last week without little improvement.  I did find out that my C2 & C3 vertebrae are showing fusion, which I don’t know if my neck/spine could be playing a part.  I have read that the vagus nerve is in the area where the hiatal hernia is occurring, so I am wondering if that is the issue.  I had an EBCT scan done, and there was a 2mm kidney stone found, and possible fullness in my pancreas.

Lyme Disease test came back negative.  My EBV VCA IgG (>749.9) and EBNA were positive, and IgM was negative.  Gastro didn't find anything.  Some of my symptoms are improving, so I am waiting to see what happens at the dizziness and balance clinic next week.

Sorry, the nurse practitioner was with a neurology group.

ENT, and nurse practitioner in the beginning, and then a Cardiologist.  I have an appointment with my Gastroenterologist next week, and I am calling today to make an appointment with my mom's Neurologist today.  I am going to a dizziness and balance clinic at Emory next week.
