Fix Your Back Pain. Sore Back. Poor Posture.
Back pain is such a powerful thing it can actually "switch off" some of the deep muscles close to the back and neck. This can happen very soon after you first get a back pain (possibly within the first 48 hours).
The deep muscles in the lower back and abdomen normally provide support to the bones (and discs) of the lower back area when you move around.
The deep set of muscles in this area are often referred to as your "core stabilising muscles". Sometimes the core stabilising muscles are likened to a "deep corset".
It doesn’t seem logical that when you have back pain, the supporting muscles go on a holiday, and stop working for you, but it’s true see the evidence for back pain treatment.
