I had the  rhizotomy done 12 days ago and am having worse pain now then I've had before. I've been fused twice have had numerous epidurals as well as facette injections. I went back to pain dr he wants to do more epidurals. I'm scared now.  I have severe headaches now and shooting pains from my head down my neck and left shoulder. Had anyone experienced this?  Did it ever very better?
