@martyk -- There is a discussion you might find helpful for DRG spinal cord stimulator.

DRG (Dorsal root ganglion): https://connect.mayoclinic.org/discussion/drg-dorsal-root-ganglion/

My trial SCS was with Boston Scientific. The trial was aborted as my Pain Mgt. Doctor is an anesthesiologist who irritated a nerve while attempting to thread the probe from the L5-S1 region into thoracic area. After experienced this, along with me being on blood thinners, I decided not to tempt fate any further. My PCP was the one who recommended a trial dosage of Cymbalta (30 mg) for at least a two week period to allow my body to adjust to it. She also suggested using 5% Lidocaine gel as a supplement. I also continued taking 7.5 mg of oxycodone at 6hr. intervals. After a four week trial at 30 mg, the dosage was increased to 60 mg. I'm not experiencing any harsh side effects which I had with Lyrica and gabapentin, and my oxycodone consumption has reduced 25%. My intention is to further decrease my oxy this month to a 5 mg tablet that will sustain relief for 7-8 hrs. That in effect will result in a 50% reduction. I'm just taking it a day at a time.
