I have had cervical degenerative disk disease since 2015 along with my fibromyalgia and all. Some of the best investments I made include sleeping on my back on an Original McKenzie Cervical Roll (insert with existing pillow) and using a neck pillow while driving or riding in a car. The model I have isn’t available currently, but there are many car neck pillows out there. Please note, both of these were stiffer at the beginning, but both softened nicely over time—especially the McKenzie roll. I also will use a neck pillow in the house while in a recliner or whatever too. I personally am not a fan of the neck brace idea as it will weaken your muscles to stay in that. It would be better to try to get physical therapy and develop a safe stretching and exercise regimen for your neck to help the pain that way. Obviously that is only my personal take. Consult your physician for their thoughts.
