No so bad today but yesterday was a killer

So This morning I am up with minimal pain, stiffness is still there such as just driving to work.  I got out of the truck, and just really stiff.  Going to the chriopractor this monring (Dr.Dan)  so we'll see what happens there.  Yesterday though was a different story.  Yesterday I hurt all over, and i had 10 people over for Easter, what a pain.  The only thing I could attribute it to was I had run, litterly run from teh grocery store out to the truck  on Saturday becasue I left my debit card in the truck.  I was already at the check, felt like an idiot, but anyway, I wasn't parked that far away, Saturday night things started hurting and I tossed and turned all night.  Everything ached, all that from just running a few 100 feet, what is going on here?
