Although I am NOT equipped with an upper buzzer to adequately respond to your inquiry. I can and do pray regarding the severe upper half pain issues with which you deal.
I do know about arm and hand pain and tingling, loss of feeling in hands so could neither type nor write a word. I could not drive or dress myself. I was losing the use of my arms before the fusion.
I cried from the pain. Sobbing because it was not manageable even with morphine. So I do empathize.
Out of this knowledge I PRAY for you that all will be well.
Fiona, who has written here very recently DOES have twin buzzers, one is cervical. Search Fiona posts under her posting name fionab and start going backwards if you want with her most recent post by going here-

She especially had good results after her twins were implanted. A recent fall, though, may have caused lead migration which has hurt the benefit of her upper SCS.
