I guess I missed something because I thought you wrote you told the dr that "you did not fill the vicodin" and then that you had it filled ahead of time with the other meds. Dani is right about all the acetaminophen in the meds as it is in the percocet and the vicodin. I do not know what strength you had of vicodin, but the percocet has at least 325 mg in each tablet. as does the vicodin. She also gave you an easy out by calling and putting the vicodin on hold for now. The script is good for at least 6 months, when you run out of percocet, call in and have the vicodin filled then.
As for the ablation, I had that done, and the initial test injection did give me some relief. When I went for the procedure, it did not offer me any relief. I talked about this with the PM anesth. that did it, and he said unforunately, the lidocaine was wonderful at numbing the site, and if he could find something that worked as well, but lasted for months he would be a bucket the size of CUBA, but it was not possible with the meds at his disposal. When I got home I read that the ablation could be repeated up to 3 times, and then it would not be recommended to do it again. I had two points done on my back, one I never felt the vibrations, etc I was supposed to feel prior to the injection, but he gave it anyway. The other he inserted the needle/probe, and I jumped two feet off the table. I apologized for jumping, and he apologized over and over for hurting me. I did not go back, as during this visit, I told him my PM dr at home was leaving town, and should I see him now for my meds . HIS reply: "I do not know anything about that, all I know is I am doing this procedure." He did not offer any suggestions. I know his office does do scripts, as both my visits to him (100 miles away) were interupted by a patient having trouble securing his meds the way he wanted them. Good luck with the ablation should you decide to do it, it could work for you. But just because the trial injection works , it does not mean the ablation will give the same relief. If you can afford the procedures, and have good insurance, it could be worth at try.
PM drs are difficut to come by, and it takes years to build a trusting relationship. Be very careful of violating that trust. Some PM only want to do procedures, some will do only medication management(few and far between for really good ones) and others do both.
