Hi PerthMum,
I had the same unit implanted 5mths ago and am still having issues.I have intermittent burning pain which seems to be related to 'pocket pain' at the battery insertion site.Have tried various things including compounded analgesic creams of varying strengths (Capsaicin,lignocaine and Clonidine) which eased the burning sensation but only whilst I continued to use it ,stimulator reprogramming,increased dosage of gabapentin (only recently increased so can't report on it's effective as yet) and am soon to undergo bilateral blocks in my lower back.I have also been experiencing extreme sensitivity /pain from the actual scar at the battery insertion site so on the same day that the blocks are performed I will be having platelet rich plasma therapy .Fingers crossed that something will help
