That sharp, nagging pain on one side of your lower back? 😣 It’s often caused by a tight and weak QL (quadratus lumborum) muscle.
This small but powerful muscle runs along the side of your lower spine and helps stabilize your pelvis and support your posture.
When your QL is tight on one side and weak on the other, it can pull your spine out of alignment, leading to discomfort, uneven posture, and even issues with movement over time.
Simple stretches, targeted strengthening, and awareness of how you sit, stand, and move can make a huge difference in preventing chronic pain.
