Hi, I've had crps spread to my lower back following a scs implant surgery to treat crps in my right arm. I have tried and been in all the medications that are recommended, I've had 4 ketamine low dose infusions, ive had 2 nerve blocks but nothing is working. I have all the symptoms of skin colour changes, night sweats, aching, burning pain, tightness/pulling feeling as well as shiny skin around the spinal incision where the leads were anchored. My pain specialist as well as the SCS implant representative has said that this is a new chapter for them! Everything feels like a guessing game! So I'm asking has anyone tried the fentanyl patches for pain relief or has anyone had a pain pump that had helped?
