I have had my Boston Scientific stimulator since 2012. That was replaced in 2018 with a newer model. I find it very helpful for my neuropathy in my legs and CRPS in both feet as well as lumbar pain due to a variety of problems. I now use it 24 hours a day with night time use being on silent or close to it. I am allergic to many meds that might help, but I find this much more acceptable. Have any questions I might be able to answer, I'd be glad to. I also have pudendal nerve damage from the first child birth experience 45 years ago next Tuesday!- I don't have pain, just loss of functions.
