Hi Tracy,
sorry to hear the SCS is giving you that level of relief. I have one that has moved - it is an 8 octad lead addressing lower extremity CRPS that is extreme to say the least. Had a huge issue with the pain sp. to get new films of it - turned out it had actually moved enough to be touching the wrong nerve root. It was like I had urinated on an electric fence when activated on any program(a somewhat mild but crass description).

They did not review!
I do hope this hasn't happened to you.....but it might be worth a look - an X-ray is not too costly & could yield a great deal of diagnostic value & peace of mind. Even if the lead has been in place for the time you mentioned, I recently found some meta-analyses based on a number of practitioners implanting this technology from several different countries & the consensus was that a high percentage of leads do move.

I'll cross all appendages that can be crossed in the hope you get more relief very soon.
