I was waking up and while half awake half asleep I flinched and twisted and felt something pull in my upper back near my left scapula.
Now it's really tight and painful. Turning my head either way hurts, the more I turn it, the more it hurts.
Same if I tilt to the right (right ear towards right shoulder).
The other way the pain hits immediately - I've got no range of motion without pain.
My arm moves fine.
I'm guessing it's my levator scap - any ideas what I've done to it and why?
