Back pain is the leading cause of disability worldwide, affecting up to 80% of people at some point in their lives. In Korea, sedentary office work, prolonged sitting, and lifestyle factors contribute significantly.
Back pain affects the lower back (lumbar), middle back (thoracic), or upper back (cervical/neck area). The lumbar region is by far the most commonly affected. Back pain may be acute (lasting days to weeks), subacute (weeks to 3 months), or chronic (more than 3 months).
In Korea, the combination of long working hours in sedentary desk jobs, heavy commuting, poor posture, and reduced physical activity creates ideal conditions for back pain. Construction and manual labour workers also face high rates of occupational back injury. Prolonged floor-sitting, common in traditional Korean dining and living spaces, can also strain the lower back.
The good news is that over 90% of acute back pain episodes resolve within 6 weeks with appropriate conservative management, including physiotherapy, exercise, and pain management. Surgery is rarely necessary and is reserved for specific structural causes such as herniated discs causing nerve compression.

- Mechanical back pain: worsens with movement, improved with rest — most common type
- Inflammatory back pain: worse with rest, better with movement — may indicate ankylosing spondylitis
