question: I ride bmx, and recently I fell backwards pff my bike at a decent speed. I dodnt think much of it but minutes later I started feeling pain at the bottom of my spine. It bothered me the rest of the day. The next say I rested and did minor activity and the pain lessened. I went to ride my bike again today at the skatepark and the more active I got, the more I started feeling the pain come back. Anything I can do to recover?
