Like I said, even doctors were duped by the Stimwave founder & CEO, they were given dummies. Nerve ablations are usually required before you can even trial a SCS. It sounds like you don't even know which SCS was implanted. I am so grateful for the Boston Scientific Wavewriter SCS, it's giving me most of my life back. Get all the facts before you comment to others that are looking for help on this forum. I research things especially before offering opinions to others seeking help. At least get the facts straight. Your friend may have a really strong case, especially if he was given the "dummy".
