A common cause of back pain is injury to a muscle (strain) or ligament (sprain). Strains and sprains can occur for many reasons, including improper lifting, poor posture and lack of regular exercise. Being overweight might increase your risk of strains and sprains affecting your back.

Back pain can also result from arthritis and other age-related changes in your spine, from more-serious injuries, such as a vertebral fracture or ruptured disk, and from certain infections.

Possible causes of back pain include:

  1. Ankylosing spondylitis
  2. Endometriosis
  3. Fibromyalgia
  4. Herniated disk
  5. Kidney infection (pyelonephritis)
  6. Kidney stones
  7. Obesity
  8. Osteoarthritis (disease causing the breakdown of joints)
  9. Osteomyelitis (a bone infection)
  10. Osteoporosis
  11. Poor posture
  12. Pregnancy
  13. Rheumatoid arthritis (inflammatory joint disease)
  14. Sacroiliitis
  15. Sciatica
  16. Scoliosis
  17. Spinal fractures
  18. Spinal stenosis
  19. Sprains

Causes shown here are commonly associated with this symptom. Work with your doctor or other health care professional for an accurate diagnosis.
