Hi all I'm 19 and having trial for Nevro stimulator next week. I have chronic daily headaches lasting around 3 years, I was hoping I could get a bit of info from start to finish about having a Nevro. This battery will be under my arm has anyone had this most Iv read is in buttocks. What is a paddle? Are you asleep for trial is it painful afterwards. What's average trial time? Any info about the op or useful info would be much appreciated getting anxious.
