Back Pain Over View

The vast majority of low-back pain is muscle pain.  The cause is typically muscle overuse resulting in muscle spasms and trigger-points Low-back pain can also be Sciatica – which can be entrapment of the nerve root as the nerve exits the spinal column, but more commonly is entrapment of the Sciatic nerve by the Piriformis muscle
Low-back pain is often associated with the curves of the spine – scoliosis  and kyphosis.  A forward rotation of the pelvis often causes a sharper curve in the lower back which will stress the spine, and may cause disc problems.  Similarly, a leg length discrepancy typically un-levels the pelvis, giving rise to scoliosis.  Poor posture is recognized as a major contributor to low-back pain.
