I'm following your story; I was diagnosed with sensorimotor polyneuropathy. Mine seems to be a slow progression since first symptoms 10 yrs ago, but during the last 2 years is when my motor nerves are being affected. I was able to emotionally handle the sensory symptoms but find myself struggling with coming to terms with motor symptoms. I have also had some spinal issues, but that really just muddies the water. Which symptoms come from spinal (mechanical) issues and which from the neuropathy from unknown casue? I really can relate to your frustration.

Good luck with your emg, and I look forward to your posting your findings.
