I do not want this to influence your decision. I have a Stimwave in my upper thoracic, implanted in 2017. I am currently in the process of having Stimwave now remove it which has not been easy. The pain relief had stopped by 2018 and I discontinued use for a few months. The pain was so severe I decided to try again. By the beginning of 2019 I began falling, while completely conscious. Seizure or dystonia type activity began at the same time, even after discontinuing use right away. They believe it has migrated. I am not only in pain from my original conditions now, but also at the placement and anchored sites, with continued dyskinesia and muscle spasms, some to the point of muscle lock at the anchor site. This may have been Dr error however cannot be sure until they finally get me imaging. Good luck!
