I had the genicular nerve test on my knee last week under fluoroscopy. It was painful but only lasted about 20 mins and then sent home w/a pain journal. I was told that the first 24 hrs are the most important to monitor to help the M.D. decide whether or not you are a candidate for the ablation I was pleasantly surprised to feel relief within approx.30 minutes. After 2 yrs of chronic pain, I thought-wow this it!.... I felt so good that I decided to do some holiday shopping and braved a mall, the 2nd hour passed almost pain free and I was elated. The third hour, I felt myself regressing a bit and came home thinking:"Did I over do it?" There were no post op instructions. At the end of the 4th hour my pain was back full on at a 9-10. I was devastated. My understanding was that it"works" for approx 70 % of the candidates and confusedly diagnosed myself as not one of those fortunates. Anxious for some answers, I met with the P.A. today who reviewed my notes ...was told that I Am a candidate for ablation. I am surprised as the relief was so short lived. My insurance co. refuses to pay as mentioned before hand and Yes, it is performed at a surgery center with "twilight" anesthesia and will cost me out of pocket approx $4,000.00, and there are no guarantees.
