Good to "see" you again! I am happy to hear that your current SCS is helping you. But sorry to hear your wrist is bothering you so much. I can't answer the travel questions, but I can tell you about my "twins". I have two SCS - thoracic and cervical that were implanted at the same time. My cervical SCS actually works better for me than the thoracic one does.

You can move your neck during recovery, but you don't want to twist a lot (same as like your thoracic SCS). While you are learning the right programs for the cervical, you can get small jolts when you turn your head or tilt your head. That eased up in time. My cervical SCS has cut my pain in my hands and arm drastically. It actually gave me the use of my hands back. I am so thankful for them both!!

Well, I gotta run...got a drs appt. Let me know if you have any questions!
All the best,
Nanc
