Low back pain can be caused by tight hip flexors. The hip flexor muscle group is made up of the psoas, iliacus and rectus femoris (part of the quadriceps) muscles. When tight, they pull the low back into a hyperlordosis, or an over-arch. This causes pressure on the lumbar disks, leading to pain and stiffness of the low back.
The hip flexors can be loosened with a simple runners stretch. You can do this at home finding complete low back pain relief, or it might be a good temporary fix before you get in to see your sports chiropractor.
