God bless you and I have many of the same conditions that you listed. I also suffer from ulnar nerve damage in my right arm/ hand and underwent 4 surgeries at the elbow level and hand. They are aware of c5/6 & c6-7 nerve compression but can’t seem to get help from anyone. Oh, herniated disc at c2-3 and in lumbar region. No longer able to get pain meds as that was the only thing that helped me and I was very responsible using my Norco’s. Tried so many things, I can’t even list them. Ever had surgery on my neck or back and pray I can avoid it. Handling Workers Compensation claims for over 20 years, I never had a claimant get relief from spinal cord stimulator but rather caused more damage and doctors labeled them with failed back syndrome. Medicine and procedures change and hopefully if u go this route they can provide you the success rate. I also have Fibromyalgia, chronic fatigue, severe depression all a result of years of neglect from the many doctors ignoring my complaints of pain and burning in my hand. Well now it is in my feet, right worse with atrophy.
I am curious what u find out and the outcome if you move forward with the procedure.
They need to allow us chronic pain suffers pain meds. Very cruel, but good luck and your not alone
