I have tried the spinal stimulator. As far as working, it did as promised, except I was under the impression the battery would last much longer than it did. Mine lasted a little over 2 years. When it was replaced, and the stimulator moved just a little because it turned out to be too close to my spine, it became infected. I had to be rushed to the hospital, and it was a mess after that. That was right before the Covid came out . Days before!
I have since been taking Lyrica. I am very pleased with it.
