Symptoms: severe pain over the back which may radiate down to the hip, leg and feet. If nerve roots are compressed by prolapsed tissues, more severe symptoms like sciatica, incontinence and lower limb muscles atrophy would be encountered.

Consequence: disc herniation, ITB abrasion syndrome, piriformis syndrome, etc.

Causes: usually caused by improper posture or trauma. For example, heavy lifting with trunk forward bending posture. Long term high-heeled shoes wearing, obesity and improper sitting posture would also give rise to the development of back pain.

Back pain introduction:
Spine consists of vertebras. If the vertebras are displaced and the spinal nerve roots are irritated, pain and lower limb numbness would be reported.
