Hello I took a fall today while riding a horse. My lower back is bruised and swollen and hurts a lot even though I m applying ice and have taken a pain killer. It s been about 3 hours since the incident and I m having a hard time walking, my left leg and lower back feel extremely stiff and it hurts for me to walk. I have fallen like this before and although get bruising and soreness, I ve not had this problem walking. Should I get x-rays?
