Does anyone know what other factors cause intense neck pain besides compressed nerves?
In the last few days I haven't been able to sleep despite Nortriptyline 20mg at night.

When I place my right side of my head on the pillow, almost immediately, I feel a mounting pressure on both sides on the base of my neck which increases as I lie down. It feels like a compressing feeling that moves downwards. The anxiety and stress go up despite slow breathing techniques.

I wanted to know if muscles, ligaments and tendons could contribute to the increase in pain.
Can spasms cause this?

Thanks in advance
