I've had 6 PNS units over the last eight years and 1 SCS. I now have a intrathecal pain pump and I am down to a 7 on the pain scales most days. I have my life back and wish I had never gone through the other units. It's nice not being plugged in to a wall outlet anymore and although one unit is still implanted and "dead" it will not be removed. I just gave my battery charger pack to someone across the country who needs it. I'd be happy to answer any questions also. I've had 69 surgeries so I'm pretty knowledgeable lol
