just wanted to update. I am receiving an epidural at L4-S1. She said it would help foot pain. Not spasm. But if she call reduce or illuminate my pain at these spine levels I will be a new person with a new lease on life. She will work on upper spine after we deal with lower spine. So, I had to ask her because the nm dr told me when I asked if such a procedure she woud recommend. She said, No. Because it would affect balance. So, for a year I’ve been suffering needlessly! I’m not happy with the nm doctor!!! She said the ablation is for if the pain is not helped for long enough of a period of time. All and all and eduction.
