Causes of back pain

Back pain is more common in tasks that involve:

  • lifting heavy or bulky loads;
  • carrying loads awkwardly, possibly one handed;
  • repetitive tasks, packing of products;
  • long distance driving or driving over rough ground, particularly if the seat is not, or cannot be, properly adjusted;
  • stooping, bending or crouching, including work at PCs (poor posture);
  • pushing, pulling or dragging heavy loads;
  • working beyond normal abilities and limits;
  • working when physically tired;
  • stretching, twisting and reaching;
  • prolonged periods in one position.

Warning signs

If you have severe pain which gets worse over several weeks, or if you are unwell with back pain, you should see your doctor.

Back pain is not usually due to any serious damage or disease. The pain usually improves within days or a few weeks, at least enough to get on with your life. Only a few people have back pain that is caused by a more serious issue such as a slipped disc or a trapped nerve and even these usually get better by themselves.

X-rays and MRI scans can detect serious spinal injuries which are very rare but they don’t usually help in ordinary back pain.

If you do have back pain and suddenly notice any of these symptoms, which are rare, you should see a doctor straight away:

  • difficulty passing or controlling urine
  • numbness around your back passage or genitals
  • numbness, pins and needles, or weakness in both legs
  • unsteadiness on your feet
