Lower back pain is one of the most common reasons to miss work and leisure activities that are important to us. It is a painful and frustrating experience to suffer from unresolved back pain. The back is a complex structure, made of muscles, bones, joints and ligaments. Although it withstands extreme stress, it can be injured accidently from a heavy impact, but even a simple action such as turning over in bed can twist the spine just enough to cause a back injury. Other causes of back pain can include poor posture, arthritis, obesity and stress.
