I had radiofrequency ablation on the left side of my neck due to severe pain and headaches after a severe auto-accident. I was promised to be pain-free before I left after the surgery. I tried to tell the doctor my neck hurt worse than when I came in, but was ignored. After a weekend of the worse pain I had ever experienced I returned Monday morning to my regular neurologist. After 22 trigger point injections (marcaine) the pain finally began to subside a little. The procedure went so badly I was not even charged for the surgery. I would not recommend this procedure to my worst enemy!
