I failed the tilt table test. I also have orthostatic hypotension and the doctor thinks I have trigeminal neuralgia. I haven't received the results yet for my syn-one test. I'm able to walk my dogs for a couple of miles each day. I'm good as long as I keep moving during the day. As soon as I quit for the day my symptoms crash. I know what you mean about Chicago weather, I am from the region. I'm going to Mayo in September. I've been going to the University of Chicago for all my tests.
