There is also a device called SPRINT pns [pns is peripheral nerve stimulation] where there is a 1 week trial period. If the trial period looks good, the testing would continue for 2 more months and the device would be removed and you should be good for the rest of your days. IIRC I looked it up and OOP cost for the trial period is somewheres around $1,000.
