Hello, I thought the video was very informative. I have had chronic pain since 2016 after a cervical fusion and a failed shoulder replacement, as well as back pain that is worsening. However this new pain started about 4-5 months ago and is worsening. My EMG shows possible small nerve fiber neuropathy buy the cramping in my legs is getting worse as well as my back pain. Seeing my Pain Dr as well as primary this week . My hydrocodone is only taking the edge off. I also take 2400 g of Gabapentin a day.
