I Am A 53-year-old Man. Early This Morning, While Asleep,

I am a 53-year-old man. Early this morning, while asleep, I tumbled out of my bed and landed on my head and the right side of my back. My head feels fine, but I have significant pain around and below the ribs on my right side. Sitting up straight, and walking also hurt. I took a hot bath and used a heating pad. I also took a couple of muscle relaxers (Robaxin) that I had purchased in Canada on a trip earlier this year. Any thoughts on other things I should do? Thank you! Dave
