QUADRATUS LUMBORUM PAIN CAN BE CAUSED BY MANY THINGS, INCLUDING:

Too Much Sitting

Constant contraction or tightening can occur when you sit for long periods of time.

Muscle fatigue can be caused by constant contraction. It can become painful and inflexible if the blood flow to the muscles is reduced.

Poor Posture

Bad posture can cause pain by placing extra stress on the quadratus Lumborum when you are standing or sitting.

The muscle can become tight and sore by sitting too low, leaning on one side or slouching.

Weak Muscles

It can make other muscles work harder if the Quadratus Lumborum muscles are weak. The quadratus lumborum must work harder to support the body when other muscles in the pelvic and back are weak. The quadratus lumborum muscles can become overworked and tense eventually.

Unequal Leg Length

An uneven leg length can put additional strain on many muscles, including the quadratus Lumborum.

If one leg is shorter or longer than the other, the pelvis could be higher on the side with the longer leg. Tilting of the pelvis can also cause a shorter quadratus lumborum which can strain the muscle.

Trauma

The quadratus lumborum, like any other muscle, can be injured. Quadratus lumborum pain can result from injury to the quadratus lumborum muscle due to a sports injury or a car accident.

An injury can also result from common everyday activities. The quadratus lumborum can be injured by incorrect or awkward lifting of heavy objects.
