I'm aching, too,
I'm cold and stiff,
Could be the flu...
Just since last night.
All day I thought the sneezing and nasal drip was still just a reaction to the dust, but by bedtime my throat was getting scratchy and the ache in my knees had spread to almost every other joint...
So, it's either keep moving and hope that if I ignore it enough it will go away... or cave and just go back to bed.
We'll see how the morning progresses!
