I had an implant in 2008 to treat migraines and it worked for about fifty percent of my specific targeted pain. This year I had the original removed and a new one (the Mini) implanted with paddles in my epidural space to treat neck and limb pain (right arm and shoulder). Last week I had a second surgery to connect new wires to treat the original migraine pain. Now the little battery doesn't seem to be holding a charge and isn't supplying enough power to treat the targeted areas. Please understand I am still recovering from the surgery and the company rep. is going to do her best to change the configuration. If new programs don't work I have to either have a second mini implanted or a larger battery. Wish I would have done my research on the recent problems the company and device is having. My 2008 implant was a life changing event, this year I feel I went backwards...
