Thanks guys... The tests you mention sound about right. He explained that the tests will point to what part of the autonomic system is defunct. I don't seem to have fluctuations in my BP as in POTS, but I do have significant increases in my heart rate when standing. Along with the other lovely symptoms I have mentioned before. He may also do a test to check the fluid in my eyes as I have seem to have sicca syndrome, although, my sjogrens titers are negative.

He feels it is autoimmune, not sure what specifically, but autoimmune.

My bladder has also been acting up a bit more (retaining urine) and he has asked me to have a dynamic flow study as well. I feel fortunate to see him, Dr. Khurana, he is an 'expert' in autonomic neurology.

Are you continuing to feel better Cy?
