Hurting for no reason

I awoke this morning with a terrible back ache. I haven't fallen, have not done any heavy lifting, in fact I have barely exercised at all this weekend. I must have been doing strenuous labor in my sleep. The pain has made me grumpy and today has not been the best of days. It was a taste of spring outside, sunny and 51 degrees, and I did not venture out of the house.

I hope a good nights sleep fixes this unusual back pain, but then again it would seem that is exactly what made it hurt in the first place.
