Yes, several over the years. It is called radio frequency nerve ablation. It destroy the netrve fibers sending pain to the brain. Its been very helpful in reducing and for a time eliminating pain. I have had a very good response with it, just had one done last month. They give you numbing shot or sedation if you wish. It takes a few minutes and relief can come immediate up to 2 weeks and last depending on your body. God bless you Kathy
