The vascular surgeon wants to send me for an angiogram because he suspects there may be something dysfunctional in my neck because I feel dizzy and nauseous if I tilt my head back and look at the ceiling. I went to him because when I use my arms to pick something up I can experience immediate symptoms and need to be horizontal for at least 20 minutes so my body regulates itself. I'm very sensitive to motion-sickness - for example, on the weekend I looked through a pair of binoculars for perhaps 10 seconds and the unstable image caused a couple of hours of nausea. I can't read in a vehicle, vomit on planes, boats, etc, etc. So I don't think there is something wrong with my neck and I'm not sold on this invasive procedure with a 1 in 1,000 chance of a stroke. Has anyone found an angiogram helpful with ME symptoms? Harmful? Thanks.
