Rest and Recovery 12-24 and 12-25

I had originally planned to do the 12 days of Christmas WOD at Maxability Crossfit on Saturday morning but by Friday night my triceps were wrecked.  I'm not sure what exercise caused all of the damage.  They were so sore and swollen that I couldn't scratch my head with either arm.  This is the worst bought of soreness I have had in years.  Not sure it it was brought on by hitting things too hard after taking 2 weeks off or whether lack of sleep and dehydration was a factor as well.  Im sure they all contributed to the cause.
