I tweaked my back somehow today at work, no idea how or when, just out of nowhere it started hurting in one spot so much I couldn't take a deep breath and it was even hard to talk for awhile. When I got home I went and sat in the hot tub for a little bit, and now I'm relaxing with a glass of wine, I think the knots are starting to work their way out. It was an extremely busy day my calls were literally back to back until about an hour before I came home.
