@jesfactsmon I have no idea if this would apply to the device Linda has been trying, but when I was undergoing the trial with a Medtronic spinal cord stimulator, I found the most pain relief with a very, very low setting. When I mentioned this to the Mayo nurse and the Medtronic rep, they said that they have found that the lowest setting that's effective is best, and that they try to tell people not to continue raising the number and expecting more relief. Hope this helps.
