I will pray for a great outcome for your surgery. I prefer my pain management doc as I am allergic to so many medications, including MAC anesthesias. He has helped me significantly with radio frequency ablations. In some places I have had close to two years relief. I hate headaches and an injury to my neck gave me occipital headaches. It's been a year since I had the last rfas and I am still headache free. He has also done some on my lower back with success. Not sure how long this latest series have been doing their thing.. With the stimulator I have seven programs and a variety of pulsations. It can take adjustment to the stimulator to get the best for you. I just turned my feet one on. You mentioning that reminded me I have that available.. Feels pretty good while sitting!
