Three nights ago I fell and ever since my back is sore and my actual spine hurts. My DH had just got out of the shower and didn't bother to wipe up the puddle of water on the floor, So when I walked in to use the bathroom my feet came out from under me and I fell flat on my back. It's like over the days the pain gets worse. What's the worse I could have done? Is it with a trip to the doctor?
