Hello! I have herniated, buldging discs. Please excuse the mis-spelling. Anyway, My Dr. has inserted needles at the top of my neck all the way down my spine. He called it an ablation. What does that do? and how does it work, and how long does it last?
Dear patient nerve ablation treatment is done for facet pathology with insertion of needles and not disc ablation.  For nerve compression due to disc prolapse local injection of corticosteroid into epidural space helps. This is done only at the level of disc prolapse. I think in your case nerve ablation is likely done. This will help in relieving facet joint pain by affecting pain pathway. Relief by nerve ablation is usually permanent.
