Pain. The ribs in my lower back are sore, feels like bruised ribs but I can't account for any activity that would have caused that. Hurts when I move suddenly or stretch too far, when I breathe deeply or laugh. As victim of crime in my younger days I know what a stabbing wound feels like. It's not that sort of pain though.
In addition there's an unexplained ache in my right shin. Seeing my GP about it in 14 hours time.
