Lower back pain
The lumbar spine takes on an enormous amount of stress. It connects the upper half of your body to the lower half and involves twisting and bending between the two. The overuse or misuse of the muscles in the back can cause a gradual growing ache which if left can cause extreme pain to strike suddenly.
Symptoms
The pain is between the bottom of the ribs to the area just underneath the buttocks. It may or may not be accompanied by leg pain, or sciatica. It is often an acute onset, with stabbing pain, forced posture and movement locking.
