@ssonkin, fellow members like @stantallusa @lowth21 @olanordman @ken82 have talked about experiencing pain long after surgery. Might your experience be similar to any shared in these 2 related discussions?

– Lower spine pain after robotic Prostate removal https://connect.mayoclinic.org/discussion/lower-spine-pain-after-robotic-prostate-removal/

You sure have good results with your recovery otherwise. I sure hope this gets resolved. Have you talked to your surgeon and the pain and the report about the nerve sparing being "fair" on the left side?
