Thanks @julkun. If insurance approves the procedure, I will be getting the permanent implant. So, the odds are against me in that regard. Even if approved, there are no guarantees that the neurosurgeon will be able to remove enough scar tissue to get the lead in the sweet spot. Then, there's the question of whether the device will give me any real relief. At this point I can't sweat it. God is in control. I am completely in His hands.
Thanks for your kind words. I hope and pray that your trial is a smashing success.
