Welcome to the forum!

I saw your other post and am glad to hear that your trial went so well. So, now you're in the big countdown! I know how hard it can be having to wait for the permanent implant after getting such good relief from the trial.
I don't have a cervical unit, so I'm not much help. The hip/waist battery placements are usually for the lumbar. I've heard of some having the battery put in the front side near the abdomen.

There are quite a few cervical SCSers here and they will give good input.
It's great to have you here! Be sure to keep us posted!
