A rheumatologist is a doctor who diagnoses and treats arthritis and other diseases that affect the joints, muscles, bones, and sometimes the immune system. They often help with long-term conditions like rheumatoid arthritis, lupus, gout, fibromyalgia, and osteoporosis.

What they do

  • Figure out what’s causing pain, swelling, stiffness, or inflammation.
  • Order and interpret tests such as bloodwork and imaging like X-rays or MRI.
  • Treat conditions with medicines and other nonsurgical care.
  • Help manage chronic diseases over time and coordinate with other specialists when needed.

When people see one

People are often referred to a rheumatologist for persistent joint pain, unexplained swelling, morning stiffness, autoimmune symptoms, or a condition that may be inflammatory rather than just a simple injury.

Simple example

If someone has ongoing swollen, painful hands and testing suggests rheumatoid arthritis, a rheumatologist would confirm the diagnosis and build a treatment plan to reduce inflammation and protect the joints.
