Post-rhizotomy pain?

[LanceK]

Reporting back five weeks post lumbar rhizotomy performed on Sep. 3 and 4.

Results have been rather disappointing compared to what I experienced immediately following the medial nerve block diagnostic procedure. Whereas the nerve block resulted in immediate relief in the range of 80% to 90% pain reduction, the rhizotomy procedure itself has so far been effective only to about 50% at most -- probably less, to be honest.

I'd like to maintain some degree of optimism, but everything I've read online indicates I am already at the post-op point where increasing passage of time would be expected to produce less, if any, improvement.

If that turns out to be the case, I'm not sure what options I would realistically have for the future.

Any ideas?
