I first noticed it yesterday - fine in the morning, it got worse from the afternoon on. I only got to sleep last night because we have some great painkillers that also knock me out. This morning it's still there.
It's like the rear sides of my neck and shoulders (you know.. that line that kinda runs from your shoulders up your neck at the back) are reeeeally stiff. If I move too far in any direction it really damn hurts. I can do it - but it hurts.
Bah. Not a good time to be sick/injured/unwell.
