Thank you so very much for the information. It sure is good to hear a success story. I can't believe Medicare wastes so much money on the nerve blocks having to be redone when it has been proven that it helps. Another friend who has been having epidural steroid injections every three months for about 5 years is going to try RFA. It's a blessing for yours to last up to 3 years. I dearly hope that mine will work at all. Thanks again!
