I have a patient whom recently moved to my area from NYC with a history of MS and fact mediated pain. Has always been nervous about spinal procedures as his neurologist at major academic center back in NYC told him to never get an epidural injection. I have done lumbar MBB x2 with >60% relief each time. He talked to his new local neurologist about RFA and now doesn't want to proceed as neurologist gave vague uncertain answer about safety of RFA with a history of MS. Pretty much everything that I have read say that there are no issues with RFA in MS patients, but is there something out there that I am unaware of, or is this neurologist just being intentionally vague because they just don't know the answer?
