(HealthDay News) -- In a child, back pain is different from back pain in adults. Particularly in children under age 4, it indicates a serious underlying problem, the American Academy of Orthopaedic Surgeons says.

You should see your doctor if your child has back pain, the academy says, especially if accompanied by any of these other symptoms:

  • Fever.
  • Weight loss.
  • Feelings of weakness or numbness.
  • Difficulty walking.
  • Pain that extends through one or both legs, or if it prevents your child from sleeping.
  • Issues with the bowels or bladder.
