Curious if people here have worse symptoms in the morning vs. the afternoon?

I wake up every morning and the major malfunction is tilting my head back ever so slightly past neutral. As the day goes on and I continue to stretch my scalenes I can tilt my head back further with less referred pain down to my forearm.

Does this make sense?

Is it possible that my scalenes tighten up over night and maybe my first rib rises as well? And that this slowly loosens throughout the day?

As an aside, it's mind boggling to me that tilting my head back just a little causes such a problem. I mean, my scalenes are that tight?
