In that final hour of sleep, I had clearly slept in an odd way, and a muscle or something in my neck (in the area of the left hand side of the trapezius if you want a more exact location) had spasmed, or been strained somehow. I couldn't turn my head without pain, or lift it to look up . Work wasn't pleasant. When I got home, I applied some heat, and that really helped.
By yesterday it was feeling better, though still tender, and I was careful not to do anything at work to aggravate it. Today it's still sore, but going away nicely, but all I've managed to do over the past couple of days, exercise-wise at least, is hop on the exercise bike for a bit. I'd intended to start running thursday night now the weather is better, but that went down the pan.
I've only put this on here as an example of how sometimes, despite how well you look after yourself, the body has a mind of its own and occasionally bites you on the bum!

















... then it was ok. But by that night, I couldn't move my left arm at all. The pain was sooooo unbearable... all I did for 3 days was cry
and pray, it hurt so bad. Then it quit hurting, just like that.
