Anyone tried one of these HF-10 gadgets? I haven't yet found a reason not to try it. I'm trying to calibrate my expectations, but anything that might interrupt the signal being sent to my brain that every step or minute seated is crushing that 'pinched nerve'. The neurological symptoms are getting worse & the pain is more relentless than ever, and I'm still holding out some hope (very little) that I can avoid the operating table. Is the 'pinched nerve' at least partially caused or exacerbated by TMS / emotional causes? Almost certainly... I've just reached a point at which I'm not sure it even matters anymore. The psychological approach isn't moving the needle at all, neither are any of the modalities that used to provide at least some relief - PT, steroid injections, etc. I'm ready to hop on the operating table just because I haven't tried that yet & the risks...well, I'm getting very close to not caring much about those. Anyway, getting off-topic here...anyone tried this gizmo?
