General Malaise
General malaise is a nonspecific symptom of overall bodily discomfort, weakness, or feeling of being unwell that often accompanies the onset of various acute or chronic illnesses.

| Time | Task | Cantonese Key Phrases | Why It Scores Marks |
|---|---|---|---|
| 0:00–0:30 | Friendly opening, introduce self, confirm identity | 「你好，我姓X，係今日嘅醫生。請問你點稱呼？」(Hello, I'm Dr X. How should I address you?) | Rapport building; interpersonal marks start here |
| 0:30–1:30 | Open-ended HPI: let patient describe malaise | 「你今日嚟睇醫生，最主要係咩問題呀？可以講多啲俾我聽。」(What's your main problem today? Tell me more.) 「呢個情況幾時開始㗎？之後點樣變化？」 | Chief complaint + timeline; lets hidden agenda surface naturally |
| 1:30–3:00 | Focused symptom analysis + red flags + targeted systems | 「有冇發燒、出冷汗、體重有冇輕咗？」「有冇覺得氣喘、心跳快？」「有冇痛嘅地方？有冇瘀傷流牙血？」 See Must-Ask table below | Covers biological DDx; red flags score heavily |
| 3:00–3:30 | PMH / DHx / Allergy / FHx / Social Hx | 「你有冇長期病？食緊咩藥？有冇食中藥或者補品？有冇藥物敏感？屋企人有冇類似嘅情況？」「你做咩工作？有冇食煙飲酒？」 | Drug history a key masquerade; social Hx for biopsychosocial |
| 3:30–4:30 | ICE (Ideas, Concerns, Expectations) | 「你自己覺得係咩原因？」(Ideas)「你最擔心係咩？」(Concerns)「你今日嚟最希望醫生幫到你啲咩？」(Expectations) | Direct marks on Case Report Form Q3 |
| 4:30–5:00 | Uncover hidden agenda / functional impact | 「呢個情況有冇影響到你返工或者日常生活？」「有冇啲嘢令你最近壓力好大、瞓唔好？」 | "Why today?" — often psychosocial; scores hidden-agenda marks |
| 5:00–5:30 | Summarise back and check understanding | 「等我總結一下你嘅情況…我理解得啱唔啱？」 | Signposting + summarising = interpersonal marks |
| 5:30–6:00 | Explain plan, safety-net, close warmly | 「我建議幫你驗吓血，了解清楚原因。如果之後出現發高燒、嘔血、或者突然好攰企唔穩，就即刻去急症室。」「多謝你嘅信任，有問題隨時搵我哋。」 | Safe closure; safety-net phrase scores exam marks |
How to uncover the hidden agenda: "General malaise" is vague — patients often attend because of a deeper worry (cancer fear, work stress, relationship issue, recent bereavement). After exploring biological symptoms, always ask 「其實你今日嚟睇，最令你擔心嘅係咩嚟㗎？」 — this single question frequently reveals the RFC.
| Domain | English Question | Cantonese Question | Why It Matters | If Positive, Think Of |

Case Report Form Answer Builder
- Chief complaint: "General malaise for ___ weeks/months"
- HPI must capture: onset, duration, progression, associated constitutional symptoms (fever, night sweats, weight loss, appetite), associated system symptoms (SOB, palpitations, bleeding, polyuria, joint pain, mood), aggravating/relieving factors, functional impact, medications (including TCM), relevant PMHx
- Examples: "Concerned about persistent tiredness affecting work"; "Worried the malaise could indicate a serious illness (e.g., cancer)"; "Requested blood tests to find a cause"
- How to phrase: State the patient's perspective — why today? Use the patient's own words if possible.
| Likely Examples | Exact Wording | |
|---|---|---|
| Ideas | "I think I might be anaemic" / "Maybe I'm too stressed" / "I read online it could be cancer" | "Patient thinks the malaise may be due to ___ (anaemia / stress / serious illness)" |
| Concerns | Fear of cancer, fear of losing job, worry about burdening family | "Patient is worried that the malaise may indicate cancer / a serious underlying condition" |
| Expectations | Blood test, referral, sick leave, reassurance | "Patient hopes to have blood tests done and to be reassured about the cause" |
- Choose based on the stem — in primary care, the most likely diagnosis for an undifferentiated "general malaise" is often:
- Minimum supporting evidence: ≥ 2 positive history features + 1 physical sign (e.g., conjunctival pallor for IDA, flat affect for depression)
| DDx | One Key Discriminator |
|---|---|
| Hypothyroidism | Cold intolerance + weight gain + constipation + bradycardia |
| Diabetes mellitus | Polyuria + polydipsia + weight loss despite normal/↑ appetite |
| Malignancy (e.g., lymphoma) | Unexplained weight loss + night sweats + painless lymphadenopathy |
| Domain | Example |
|---|---|
| Biological | Anaemia causing fatigue and reduced exercise tolerance |
| Psychological | Anxiety/worry about underlying serious illness; or comorbid depressive symptoms |
| Social/Functional | Inability to work / reduced work performance / burden on family / social withdrawal |
| Diagnosis/DDx | Best Supporting Physical Sign | How to Elicit | Why It Supports |
|---|---|---|---|
| Iron deficiency anaemia | Conjunctival pallor | Pull down lower eyelid, inspect palpebral conjunctiva | Pallor correlates with Hb < 9-10; classic sign of anaemia [10] |
| Depression | Psychomotor retardation / flat affect | Observe during consultation: speech rate, facial expression, engagement | Supports diagnosis of major depressive disorder [4] |
| Hypothyroidism | Delayed relaxation of ankle jerks / bradycardia | Elicit ankle reflex; measure pulse | Classic clinical sign of hypothyroidism |
| Malignancy / Lymphoma | Painless, firm lymphadenopathy | Palpate cervical, axillary, inguinal LN chains systematically [5] | Non-tender, rubbery, matted LN persisting > 2 wks suggests malignancy |
| CKD / Uraemia | Peripheral oedema + café-au-lait skin colour | Inspect skin colour; press pretibial area for pitting oedema [3] | Café-au-lait skin + oedema suggests advanced CKD |
| Hepatitis / Liver failure | Jaundice (scleral icterus) | Inspect sclerae in natural light [6] | Icteric sclerae indicate hyperbilirubinaemia |
| Thyrotoxicosis | Fine tremor + tachycardia + lid lag | Outstretched hands with paper on top; check resting HR; look for lid lag | Classic triad of Graves' / thyrotoxicosis |
Top Traps That Lose Marks
- Jumping to a diagnosis without exploring ICE — the Case Report Form explicitly marks ICE; many students skip it.
- Forgetting to ask about depression — depression is the #1 masquerade for general malaise [4]. If you don't screen mood, you miss the most common diagnosis.
- Not asking about TCM / herbal medicine — patients may not volunteer this; you must ask specifically about 中成藥 (tablet form) and 中草藥 (herbal form) [6].
- Not asking about drugs — beta-blockers, statins, antihypertensives, and chemotherapy all cause fatigue.
- Ignoring red flags — unexplained weight loss, night sweats, persistent fever, new lymphadenopathy → must refer urgently.
- Writing "malaise" as the diagnosis — malaise is a symptom, not a diagnosis. Always commit to a specific most likely diagnosis.
- Forgetting to safety-net — always tell the patient when to return or go to A&E.
Must-not-miss red flags requiring urgent referral:
- Unexplained weight loss > 5% in 6 months
- Persistent fever / night sweats > 2 weeks
- New painless lymphadenopathy
- Petechiae / unexplained bruising (pancytopenia)
- Jaundice + coagulopathy (liver failure)
- Severe hyponatraemia symptoms (confusion, seizures)
Shortest safe management / safety-net line:
「如果你之後出現發高燒、嘔血、突然好攰企唔穩、或者皮膚變黃，就即刻去急症室。我會安排你驗血，一個星期後覆診睇結果。」
High Yield Summary
What to ASK: Onset/duration, constitutional symptoms (fever/night sweats/weight loss), mood screen (PHQ-2), bleeding, thyroid symptoms, polyuria/polydipsia, drug history (especially TCM), ICE, functional impact, and "Why today?"
What to WRITE: Chief complaint with timeline → HPI with system review findings → ONE RFC in patient's words → ICE explicitly → Most likely Dx with 2+ supporting features → 3 DDx with discriminators → 3 biopsychosocial problems → 1 physical sign with reasoning.
What NOT to MISS: Depression, drugs/TCM, anaemia, hypothyroidism, occult malignancy, and the hidden agenda. Malaise is never the diagnosis — always commit to a specific cause.

Palpitations
Palpitations are the subjective awareness of one's own heartbeat, often perceived as rapid, irregular, or forceful cardiac contractions.
Oral / Dental Pain
Oral or dental pain is nociceptive or inflammatory pain arising from structures of the teeth, gingiva, oral mucosa, or jaw, most commonly caused by dental caries, pulpitis, periodontal disease, or abscess.
