I also experience the torso tightening band & it's difficult to find a position to sleep. I also use a small pillow to my chest. One neurologist I saw prescribed Gabapentin, but I only took it for a week because of side effect concerns and the neurologist didn't seem to know what the problem was. I've been seeing another doctor who specializes in demyelinating diseases (like MS, for example). He has noted a lesion at my cervical spinal cord but hasn't settled on a diagnosis.

I will talk to my doctor about the Cymbalta & see if it helps. Thank you for posting!
