I also have many allergies to medications. I have Complex Regional Pain Syndrome in both feet and my left knee, as well as small fiber neuropathy from the knees down. Just had nerve studies done and was dx with severe distal sensory and motor neuropathy. Lots of pain involved. Last July I had my second spinal cord stimulator implanted. My first was done in 2012. I seldom take my oxycodone. I also have DDD throughout my spine and see pain management on a regular basis. I find radio frequency ablation rids me of pain from 6 months to two years! I am blessed to have an incredible pain management doctor who is brilliant, suffers from pain himself, is very caring, and has a great positive attitude.
