Fibrous dysplasia may cause few or no signs and symptoms, particularly if the condition is mild. More severe fibrous dysplasia may cause:

  • Bone pain
  • Bone deformities
  • Fractures
  • Nerve entrapment

Rarely, fibrous dysplasia may be associated with abnormalities in the hormone-producing glands of your endocrine system. These abnormalities may include:

  • Very early puberty
  • Thyroid gland problems
  • Light brown spots on the skin

When to see a doctor

See your doctor if you or your child develops bone pain that:

  • Increases with weight-bearing activity
  • Interrupts sleep
  • Doesn't go away with rest
  • Causes a limp
