OUCH!! I hurt my back last weekend while I was ...wait for it... SLEEPING! Yes, crazy I know! It really didn't start hurting until I started sneezing a few days ago. If you know me at all, you know that I sneeze really loud. One can only imagine how much pain I am in everytime I sneeze. I'm kinda a mess right now!
