question: I slipped and fell going down my hardwood stairs I fell and hit the actual corner of the stair. And fell directly on my lower left side of my back. It hurt but I got up and shook it off. Now going threw the rest of the day I am in an extreme amount of pain where I fell on my lower back on my left side of my lower back only. It hurts to the slightest touch and even driving in the car is painful because of my back on the seat. It does feel hot and slight bruising has started should I go get an xray?
