Hi Hope! I have had this done, but on my RSD affected arm. For me, the apprehension was much worse than the test. Be sure to be on schedule with your meds, wear something comfortable ( I had to lay down for mine) and try not to tense up. If possible have someone drive you so you can relax on the way to the test. You probably wouldn't need to have a driver, but I had to drive over 45 miles one way, and tend to get tense while doing interstate driving. A lot of valuable information can be found from this test, so it is probably good to have it. Good luck, Lisa
