I am having lower left back pain since a week. I work as a banker and I was recently transferred to another location. I drove my bike all the way for 600kms in a single day and two days later drove car for same distance. Since then I am having this lower back pain . Pain is only on the left side of my back. I am experiencing stiffness in my back while bending forward and also when I sit on the floor I feel the pain increase. When I bend forward I can feel the pain all the way in my left leg too. Since a week it's there in the lower left portion of my back. Kindly provide solution.
