And today one happened to me. David and I were struggling to get the west side of the shelter in place when the 4" fence rail we were using to take pressure off the corner post slipped. It fell forward into the shelter and the top caught me (completely unaware) on the spine, just above my right buttock. I screamed like a little girl, partly out of surprise, partly out of pain and partly out of fear.
Fear because my right leg stopped working briefly. It wouldn't hold me up, and I couldn't make it move after I went down. It lasted for less than a minute, and then the whole thing just went cold and numb. Our kind neighbors came by with a big bag of ice, and David hobbled me into the house where I lay iced, drugged and dazed for a couple of hours. Now that I'm up and about both legs feel as though they are made of lead, but they are holding me up and moving when I will them to move. A lucky outcome and a lesson learned.
