Lower back pain: causes and when to worry

Lower back pain is one of the most frequent reasons for medical consultation. It is estimated that 80% of people will experience it at some point in their lives.

Frequent causes

Muscle contracture: Excess tension in the paravertebral muscles due to poor posture, exertion or sedentary lifestyle is the most common cause.

Herniated disc: The intervertebral disc can press on adjacent nerves, producing pain that can radiate to the leg (sciatica).

Lumbar osteoarthritis: Wear of the lumbar vertebrae generates morning stiffness and pain.

Warning signs

When to act?

For common mechanical lower back pain: maintain moderate activity, avoid absolute rest and apply local heat. If it does not improve in 1-2 weeks, consult your doctor.
