Common Causes

A sprain, strain or spasm of the ligaments in the back is the most common cause of back pain. (1:4, 5) This can happen from bad posture (5:4) or if you lift something heavy, placing strain on your lower back. If the spine becomes overly strained or compressed, a disc from in between the vertebra can slip outwards. This can irritate the nerves that are rooted to the spinal cord, pain. (5:3,5,7)

Mostly, pain in the lower back is due to a specific trauma to the back. But it also may be due to arthritis, osteoporosis or other bone diseases. (1:1) (5:3)
