Hello, This thread is probably pretty old but I have a question that applies. I had my second Facet Rhizotomy done a few days ago (left side C3-C6) and the post rhizotomy is completly different than when I had the right side done. The left side and back of my scalp down to my shoulder blades has been numb since Thursday (it is Saturday now), I have increased pain when I turn my head left but I expected that. The numbness has me concerned.. Is this a normal side effect? Thanks, Geo
