Which doctor treats this

  • Start with your primary care provider (family doctor or internist).
  • They may send you to an orthopedist (bone and joint doctor).
  • A physical therapist can help with exercises to rebuild strength and motion.

Back to school, work, or sports

  • Most people keep up normal school and work. Rest when you need to.

Pregnancy and breastfeeding

  • If you're pregnant or planning to be, tell your prenatal provider about this condition.
  • Don't start or stop any medicine on your own. Some are safe in pregnancy and some need to be changed.
  • Ask before taking any pain reliever. The FDA advises avoiding ibuprofen and naproxen after 20 weeks unless your doctor says to.
