This is very interesting! I had my first NEVRO placed 7.5 years ago and about 2 years ago it started shocking me - badly! They swore it was impossible to be shocked but after three months of screaming in restaurants, church, stores, home, and other places where my body involuntarily responded to the shock I insisted it be replaced and it was. Unfortunately I did not listen to my doctors who warned me that NEVRO was experiencing significant employee turnover and customer support issues as well as quality issues with the newer products. All of these have affected me significantly since I had the new NEVRO stimulator placed about 1.5 years ago. It is next to impossible to get a call back for program updates - or any other issue for that matter! For example, the charger for my stimulator failed yesterday and I left messages over two days and zero response so my pain level has escalated. I have also read another person’s post on the same charger-failure issue and he was told it would take 2 WEEKS to get a new charger! Seriously? They can’t spend money to overnight a charger? I am calling my surgeons tomorrow to find a way to replace this NEVRO device with one from a different company. I did not have this invasive and risky surgery done to have an uncomfortable bulge in back with no benefit.
