Most cases of low-back pain are regarded as non-specific (a staggering 96%). A third type of low-back pain cause is a traumatic injury, such as a fall or sudden jarring of the back.

Muscle pain in the psoas is often related to tension, overuse or muscle injury from exercise or physically demanding work. You tend to experience pain either side of your lower back, during or just after activity. If muscle tension remains injuries can occur because of stress building up adding pressure to the spine and vertebrae attached to the psoas muscle.

With cases of psoas muscle tension, releasing the fatigue built up through ma...
