Hi Sandra!
I have two SCS's (cervical and thoracic), and both were initially percutaneous leads. The thoracic leads migrated within a couple of months, and the battery really irritated me where is was initially placed. Those leads were stimulating too much giving me muscle spasms, etc. I had the thoracic leads changed out for paddle leads and the battery relocated. Because I already had leads placed, they were able to use the same path when they implanted the paddle leads...a laminectomy was not necessary for me
I have not had any issues with the paddle leads, they have stayed put!! I would highly recommend them if given the choice.

Wishing you the best!
