What a rheumatologist treats, and when you should see one

What a rheumatologist does

A rheumatologist is a doctor who trained first in internal medicine or pediatrics, then spent two or three more years learning diseases of the joints, muscles, bones and immune system.

They treat rheumatoid arthritis, lupus, psoriatic arthritis, gout, ankylosing spondylitis and other forms of axial spondyloarthritis, vasculitis, Sjogren's disease, scleroderma, myositis, polymyalgia rheumatica and giant cell arteritis. They also see people with osteoporosis, and people whose blood tests came back abnormal without an obvious explanation.

Most of these are autoimmune. The immune system, which exists to attack infection, attacks your own tissue instead. That is a completely different problem from the wear-and-tear arthritis that comes with age, and it is treated in a completely different way. Wear and tear is a plumbing problem. Autoimmune disease is a wiring problem.

They are not surgeons

This trips up a lot of people. A rheumatologist does not operate. They diagnose, order the right blood tests and imaging, and manage medicines over years, sometimes decades.

If a joint is worn out and needs replacing, that is an orthopaedic surgeon. If your immune system is eating the joint, that is a rheumatologist, and the sooner they start treatment the less there will be for a surgeon to fix later.

The two work together often. What you do not want is to spend two years with a surgeon for inflammatory arthritis, or two years with a rheumatologist for a torn meniscus.

Signs that warrant a referral

Ask your primary care doctor about a rheumatology referral if you have:

• Joint pain and swelling in the same joints on both sides of the body, especially the small joints of the hands, wrists or feet
• Morning stiffness lasting more than 30 to 60 minutes, rather than a few minutes of creakiness
• Joint pain together with a rash, fever, weight loss, mouth ulcers, dry eyes or a dry mouth
• Back pain that started before age 45, is worse with rest and better with movement, and wakes you in the second half of the night
• Sudden severe pain, redness and swelling in one joint, often the base of the big toe
• Fingers or toes that turn white then blue in the cold
• A positive blood test such as rheumatoid factor, anti-CCP or ANA, whether or not you feel unwell
• New headache, scalp tenderness or jaw pain when chewing, over the age of 50, which needs to be seen the same day

Joint pain on its own, in one knee, after years of running, is usually not rheumatology.

Why waiting costs you

In rheumatoid arthritis there is a window, roughly the first three to six months of symptoms, when starting treatment prevents joint damage that cannot be undone later. Erosions visible on an X-ray do not heal.

Guidelines from the American College of Rheumatology are built around two ideas: treat early, and treat to target. That means starting a disease-modifying drug promptly, usually methotrexate, then reassessing every one to three months and changing the treatment until the disease is quiet, rather than accepting "a bit better".

The practical effect is that a referral placed in month two is worth far more than the same referral in month twelve. If your joints have been swollen for weeks, say that plainly and ask for the referral to be marked urgent.

What the first visit looks like

Expect a long appointment, often 45 minutes to an hour. A rheumatologist will take a careful history, then examine every joint one at a time, counting which are tender and which are swollen. That joint count is not ceremony; it is the measurement they will track.

Common first tests are inflammatory markers such as ESR and CRP, rheumatoid factor and anti-CCP, ANA when lupus is a possibility, uric acid for gout, and X-rays of the hands and feet. Ultrasound is increasingly used to see inflammation the hands cannot feel.

A diagnosis may not come that day. Autoimmune disease often declares itself over months, and a good rheumatologist will say honestly when they are still watching rather than inventing certainty to fill the silence.

Bring a list of every medicine and supplement you take, any imaging you have had, copies of previous blood tests, and the date your symptoms started.

The medicines, in plain terms

Disease-modifying drugs, the oldest of which is methotrexate, change the course of the disease rather than just easing pain. Methotrexate is taken once a week, never daily, and that distinction has caused real harm when it was got wrong. It is taken with folic acid, and requires regular blood tests for the liver and blood counts.

Biologics are injected or infused and target one part of the immune system, such as TNF, interleukin-6 or B cells. They are used when a conventional drug is not enough.

JAK inhibitors are tablets that work inside the cell. They are effective, and they carry warnings about clots and cardiovascular risk that a good clinician will discuss with you rather than skip.

Steroids work quickly and are often used as a bridge while a slower drug takes effect. Long-term steroids are a sign that the underlying treatment is not doing its job.

All of these suppress the immune system to some degree, so vaccination status matters, and a fever on treatment is worth a phone call rather than a wait.

Questions worth asking

• What is my working diagnosis, and how confident are you?
• What are we measuring to know whether treatment is working, and how often?
• What is the plan if this first medicine does not work?
• What should make me call you rather than wait for the next appointment?
• Which vaccines should I have before starting this, and which should I avoid afterwards?

Finding a rheumatologist who follows the guidelines

Every clinician in our rheumatologists list has had their license checked against the national registry, has their board certifications recorded, and has been screened against their public record. We show no patient reviews and no star ratings, and paying for a listing never changes who passes review.
