Back pain, or acute lumbago, is a very common cause of lower back pain. It often occurs with heavy lifting, sudden movements or rotations – but can sometimes come on without warning. The pain is intense and often leads to spasms in the back muscles, resulting in a forward-bending posture.
What is a back sprain?
Back pain is a sudden, severe pain in the lower back that often makes it difficult to move normally. The exact cause is not always clear, but the problem involves the muscles, ligaments, and joints in the back. The spasm causes the body to unconsciously seek a pain-free position by leaning forward or to the side, which in turn creates incorrect loading and increased stiffness.
Common causes & risk factors
Back pain often occurs in connection with heavy lifting, sudden movements or rotations, but also after prolonged sitting. Sometimes as little as a sneeze or a minor movement can trigger an acute back pain. Risk factors include weak core muscles, poor posture, being overweight and working positions with one-sided or heavy loads.

When should you seek medical attention?
Seek medical attention if the pain does not improve within a couple of weeks, if you experience pain radiating down your legs, numbness, or if you have difficulty controlling urine or stool.
Recommended protection & support
A back support can be very helpful for back pain.
- Stabilizing backrest that counteracts forward leaning posture and provides extra support during movement
- Compression back support that relieves pain and increases circulation
- Ergonomic aids for better posture when working while sitting
- Always combine with movement and adapted activity – complete bed rest should be avoided
