Dr Win Huang’s Clinical Reflections (1)

Doctors See More Than Disease — They See Clues

By Dr Win Huang, PhD (Chinese Medicine & Acupuncture)

Many people think that a medical consultation is straightforward: the patient describes the problem, the doctor performs an examination, and then gives a diagnosis.

In reality, that is rarely how clinical practice works.

When a patient walks into the consultation room, they bring only fragments of information.

“My knee hurts.”

“It wakes me up at night.”

“It hurts when I turn over in bed.”

“The first few steps in the morning are very painful.”

“But it eases after I’ve walked for a while.”

These are not diagnoses.

They are clues.

The real challenge is how a doctor pieces these individual clues together until they form a complete clinical picture.

Why Can Different Doctors Give Different Diagnoses for the Same Patient?

Many patients ask this question.

“Why have I seen three doctors and received three different diagnoses?”

The answer is simple: this is a normal part of clinical medicine.

Doctors are not solving a question with a single predetermined answer.

Instead, every experienced clinician rapidly develops several possible diagnostic hypotheses based on their knowledge, training and clinical experience.

What the doctor thinks determines what questions they ask.

The questions they ask determine what information they obtain.

The history they obtain influences the physical examination.

The examination then shapes the final diagnosis.

In other words, the diagnosis is influenced not only by the patient’s symptoms, but also by the doctor’s clinical reasoning.

History Taking Is About Testing Hypotheses, Not Collecting Information

Many people believe that history taking simply means recording what the patient says.

In reality, every question has a purpose.

Experienced clinicians ask questions because they are testing specific diagnostic possibilities.

If they suspect a meniscal injury, they may ask about twisting injuries, locking or pain during rotation.

If they suspect patellar tendinopathy, they will explore whether activity progressively worsens the pain.

If they suspect nerve involvement, they will ask about numbness, radiating pain or pain occurring at rest during the night.

Every question is designed either to support or to rule out a diagnostic hypothesis.

The Patient’s History Determines the Direction of the Examination

Many people assume that a physical examination means checking everything.

That is not how experienced clinicians work.

The patient’s history guides the examination.

The history identifies which systems deserve closer attention.

The examination is not primarily performed to “find” a disease.

Its purpose is to confirm—or challenge—the diagnostic impression developed from the patient’s history.

Experienced Doctors Reach a Diagnosis by Excluding Possibilities

Many conditions can produce very similar symptoms.

The key is not to think of one diagnosis.

The key is to think of several.

Each possibility is gradually tested.

Some are excluded through careful history taking.

Others are excluded during the physical examination.

Eventually, the diagnosis that best explains all the available evidence remains.

Clinical reasoning is often a process of elimination rather than immediate recognition.

Finding Abnormalities Does Not Always Reveal the Real Problem

People living with persistent pain often develop many physical changes.

Muscle tension.

Restricted movement.

Tenderness.

Compensatory movement patterns.

These findings are genuine.

However, they are not necessarily the primary cause of the condition.

An experienced clinician must decide which abnormality represents the main problem and which changes are secondary adaptations that developed over time.

Identifying the primary problem is far more important than simply identifying abnormalities.

Successful Treatment Does Not Automatically Prove the Diagnosis Was Correct

Many people assume that if treatment works, the diagnosis must have been correct.

Clinical medicine is rarely that simple.

Patients may improve because the condition naturally resolves, because they have rested, because lifestyle factors changed, or because the treatment genuinely addressed the underlying problem.

Improvement after treatment is therefore only one piece of evidence.

A reliable diagnosis depends on an entire chain of evidence.

Does the patient’s history fit?

Do the examination findings support the diagnosis?

Have more convincing alternatives been excluded?

Does the patient’s response to treatment match the proposed clinical mechanism?

The more consistently these pieces of evidence align, the greater the clinician’s confidence in the diagnosis.

What Does an Experienced Doctor Really See?

After more than forty years of clinical practice, I have come to realise that medicine is not about memorising more diseases.

It is about learning how to think.

Every sentence spoken by a patient may change the direction of the diagnosis.

Every examination finding may challenge an earlier assumption.

Every treatment provides another opportunity to test whether the original diagnosis was correct.

Clinical practice is not about finding the answer immediately.

It is about continuously developing hypotheses, testing them against evidence, and refining them as new information becomes available.

That is why I began writing Dr Huang’s Clinical Reflections.

My goal is not simply to tell readers what diagnosis was made.

Instead, I hope to share the thinking process developed through more than forty years of clinical practice.

Because, in my view, the most valuable lesson is never the diagnosis itself.

It is understanding how an experienced clinician arrives there—one clue, one question and one piece of evidence at a time.

Book an Appointment

If you have persistent pain, have seen multiple practitioners, or still do not have a clear diagnosis, a comprehensive clinical assessment may help identify the underlying problem before deciding on treatment.
