Welcome! Sorry you are having to deal with these problems!
I also have had the "twins" implanted at the same time (cervical & thoracic) but I was cut in four places....for each lead and each battery placement. I spent the night at the hospital. I also had to go back four months later to have the percutaneous leads in the thoracic stimulator changed out for paddle leads and that battery moved to the front, that was another overnight stay.
My aftercare has been pretty good. Some issues with the thoracic SCS working to full capacity, we are still working on it. My reps are great (St Jude's by the way

)
Wishing you the best!
