@wardb4 I'm sorry to hear what you are experiencing - it seems I am mirroring everything you have. I have had 2 C-spine MRIs, a brain MRI and an EMG. I also had a cortisone injection into C-7. The injection helped with the upper arm pain and the numb thumbs and fingers (due to severe spinal stenosis) - but it seemed to intensify the internal tremors/vibrations. They have become very intense when I'm in bed but do persist throughout the day. My GL insists that I have Restless Leg Syndrome and wants me to take Gabapentin but my Spine Doctor says that is not correct. So I'm seeing a neurologist the end of April. . . Hope you find relief
