Sorry to hear that.  My necks been a bit fucked up for months and I've been stretching it out but it doesn't seem to be getting any better.  What have you been doing? 

 I think this time I just shoved my neck against the headboard while I slept, probably for a few hours at a time. I can’t straighten it. 

 Damn, you must be a very deep sleeper.  GL anyway, this shit sucks and I'm getting sick of it.
