By trial, are you referring to lidocaine injection to identify the nerve? I was actually scheduled for Cervical Radio Frequency Ablation (RFA) this morning on C1-4 but postponed it. A recent Oct 10 MRI noted "extremely severe" right and "severe" left foraminal narrowing with severe AP canal stenosis at C5-6. I want to now first have my MRI reviewed with an Orthopedic Surgeon consultation. At L-4, I also had some issues with a compromised right L4 nerve root. Lots of unfamiliar terminology, Some good Mayo Clinic Spinal Stenosis videos on Youtube.

@jenniferhunter provided me with some very excellent on topic discussion and links to some Mayo Clinic Videos that help with the terminology and visual understanding of Cervical Spinal Stenosis. I did postpone the Ablation even though the Pain Management Dr said I should proceed. I am assuming that if I have C5-6 surgery, the Orthopedic Surgeon will address any C1-4 issues,

Have you seen RFA success rates? What I found was 20% to 25% full pain relief, 60% to 65% partial pain relief. It can take 4 to 6 weeks to realize these, and it may only work for 6 to 12 months. My Oncologist during my recent 6-month MGUS even cited the 60% to 65% success rate. Please do your own research though, obtain a current MRI and if warranted see an Orthopedic Surgeon for a consultation.
