question: hi there i have been getting alot of lower back pain for about a month now , i had an xray to see if my joints were ok which they were , i do alot of running and weights and i notice that one side of my back sticks out more than the other side especially after i run. My doctor told me to cut out the weights which i did 4 weeks ago. What have i done to cause one side to stick out more than the other
