I'm new to this forum. Hope I can learn more about my condition. I started having symptoms in November '08, about 9 months after having cervical surgery for stenosis (C-4 thru C-6 vertebrae were fused). I've been to multiple cardiologists and neurologists since then. Was diagnosed with NMH after a tilt table test. Have been on midodrine, fludrocortisone, propanolol (40, 80 & 160 mg), Paxil, and occasionally klonopin, but none have made any difference that I can see. Not even sure I have NMH as my blood pressure doesn't necessarily drop much when I'm dizzy and my heartbeat doesn't increase much. I'm going to the autonomic lab at Columbia Presbyterian in New York in a few weeks to see what they can find. Hope they are a good place. Has anyone else been there? I'm also on a few other medications because I had an allogeneic bone marrow transplant for Leukemia 18 years ago, but I've gone off all of them, one at a time, to see if they were contributing to my symptoms . They weren't. I've changed my diet, worn pressure stockings (awful in the summer), also tried a variety of alternative med treatments & various vitamin combinations that have been recommended to me. None have had any discernible effect. I've only passed out once, but I'm chronically dizzy and lightheaded, even as I write this. When I drive (rarely nowadays) I feel like I'm drunk after a few minutes. I've gotten pretty good at avoiding situations where I stand in one place, like check out lines during peak hours. And I've learned I can delay the onset of symptoms by jumping up and down. But there's not much I can do about driving. Because I live alone & I'm miles from any stores I sometimes have to drive farther than I feel comfortable doing. I find rides as often as I can but often this isn't possible. Does anyone else find this the most difficult problem to deal with?
