I hear your frustration and have been where you are now.

Did your neurologist do a MRI of your brain and cervical spine? Did they do a small fiber neuropathy skin punch biopsy?

You may want to see a new neurologist for 2nd opinion and an orthopedic spine specialist to check to make sure your spinal cord is not being compressed and causing your many symptoms (called cervical myelopathy).

I have myelopathy caused by spinal stenosis, degenerative disc disease, bone spurs/osteophytes, herniated disc, etc. which is pressing on my cervical spine and nerve roots/nerves and causing all sorts of symptoms below the c5-c6 and c6-c7 level. Many doctors miss the myelopathy diagnosis and misdiagnose. A delay in diagnosis can cause permanent injury so treatment is time sensitive to stop the progression. I already had ACDF surgery on c5-c6 and having surgery on c6-c7 to decompress and fuse in 2 weeks.
