I'm so glad to hear that your trial was approved & you've got a date set. From my standpoint, the trial was no big deal (although remember, my electrodes are in my face, not my back). For my trial surgery I was put under. It wasn't general anesthesia (although they used that for the permanent implant surgery), but it was some kind of deep sedation or something. Whatever it was, I was not awake and don't remember a thing. It's possible that they might keep you awake, as I hear that this is common practice with back stimulators, as they need you awake to find the correct nerve -- this is not the case with facial nerve stimulation. Anyways, good luck to you. I really hope it helps. It takes a bit to get used to the feeling (in my opinion even a week isn't enough time). I know that I liked my stim more & more the longer I had it. I've had it two months now & I am so happy with it. It certainly doesn't take away all the pain, but most days it makes a huge difference!
