@martyk Two weeks after having my new HFX implanted I started having difficulty charging it. It would charge for a few minutes and shut off. I called the Nevro rep. She instructed me how to diagnose the problem, and it was easy. She thought an electrode or connection was faulty. She was correct. A Nevro HQ tech also put me though the same procedure with the same result. Electrode/connector #5 had significant impedance. This meant that I would have to have the device and leads removed if I ever needed an MRI. NOT GOOD! I met with the Nevro rep and she developed a program that used the electrode on the opposite side of my spine from #5. It worked! I still have 100% relief BUT also still have the MRI issue. Over the next two months I tested the system from time to time with the same bad result...until yesterday! Everything tested as normal!!! I immediately called the HQ tech dept. and a tech ran me through the diagnostics again. NORMAL. He said that it might have been a bubble that somehow dispersed. He said that for 7 days I was cleared to have an MRI (not that I needed one). I will continue to do the diagnostics for the foreseeable future or until I'm satisfied that it's not intermittent issue. It's always sumtim' 🙂
