But a downside of this particular scs (Medtronic) is that in order to continue the pain relief, it must not be left switched on all the time. St Thomas’ recommend several hours on, several off – but I am finding the periods of time when switched off very difficult to cope with, particularly at night. I understand the rationale for turning the device off: if the tingling sensation becomes the body’s new baseline, then there is little room for manoeuvre with further pain relief. But this doesn’t help me when I’m climbing the walls!! Any advice from out there would be gratefully received…
