Which doctor treats this

  • Start with your primary care provider (family doctor or internist).
  • They may send you to a rheumatologist (joint and immune system doctor).

Living with it

Support groups and helplines

Children, pregnancy, and older adults

  • Children: Most start then.

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.
  • Breastfeeding: Most medicines are fine, but ask. The NIH LactMed database lists what's known about each one.

Outlook

Outlook depends on the cause; early care helps.
