Hey Yellow!
Sounds like you have some big decisions to make, and I am sure you will find the right path for you.
I am not sure if you would need to have a second phsyc eval, seems like you wouldn't need it since you already had one and a stim implanted.
Regarding charging the cervical stim - my batteries were both initially placed in my hip/butt area (one on each side), my thoracic battery was moved to my front side when they changed those leads since it was bothering me. The cervical one is still in the back. I use a belt to charge them...it's adjustable
Wishing you the best,
Nanc
