Thanks for your response!
I did have a trial with an external device and thought I had gotten some relief, not as much as I had hoped for but enough for me to go ahead with the implant. I have spoken to the nevro consultant several times and have tried different settings. The one I’m currently using acts like a very strong tens unit but it does very little to nothing for the pain/numbness in my feet.
I will be calling the neurosurgeon next week to get the device removed.
