What to Do When Rheumatologists Have Different Opinions

It can be confusing when you see two rheumatologists and walk away with two completely different opinions—one saying you don’t have an inflammatory condition and the other saying you do. This situation is more common than people realize, and there are specific reasons why it can happen.

A Real Case Example

A young woman visited the clinic with a history of migrating pains. She had previously seen another rheumatologist. Her medical background included being ANA positive and having a family history of lupus. Her symptoms sounded suspicious for inflammatory arthritis.

She had undergone an extensive workup:

  • Multiple antibody tests, all negative

  • X-rays that looked normal

  • A trial of prednisone that resulted in about 60% improvement, meaning partial steroid responsiveness

Her first rheumatologist concluded she did not have inflammatory arthritis.

During a new evaluation, however, the findings told a slightly different story. On physical exam, there was a small amount of swelling in her left wrist. An ultrasound performed during the visit also showed definite fluid in the right wrist. Combined with her symptoms, ANA positivity, family history, and exam findings, this supported the diagnosis of early inflammatory arthritis.

Why Opinions Can Differ

1. Variability in Symptoms

Inflammation can fluctuate. A patient may have more noticeable swelling or joint findings on one day and very little on another. This alone can lead to differing impressions between two appointments.

2. Meeting (or Not Meeting) Strict Criteria

Many autoimmune and inflammatory conditions have very defined diagnostic criteria. When someone clearly meets those criteria, most rheumatologists will agree on the diagnosis.

Problems arise when someone does not fully meet the criteria, but still shows concerning signs. In those cases, clinical judgment plays a larger role.

3. Differences in Diagnostic Tools

One of the biggest differences in this case was the use of musculoskeletal ultrasound.
Ultrasound is extremely valuable for evaluating:

  • Peripheral joints

  • Tendons

  • Subtle inflammation

While it has limitations for the spine, it is highly effective for arms and legs. If one rheumatologist uses ultrasound and another does not, the amount of objective information available is very different. This can easily change a diagnosis.

Why the Tools Matter

In this patient’s situation, ultrasound gave key information that wasn’t visible on exam or X-ray. That additional data shifted the diagnosis toward early inflammatory arthritis and will lead to a very different treatment plan—one that may significantly improve long-term outcomes.

What This Means for Patients

If you ever receive conflicting opinions:

  • Understand that variation can happen

  • Know that inflammation may show up on some days but not others

  • Ask whether ultrasound was used in your evaluation

  • Seek a second opinion from someone trained in musculoskeletal ultrasound if needed

Sometimes the difference isn’t the rheumatologist—it’s the tools available to them.
