- Dengue commonly causes sudden fever, headache, pain behind the eyes, muscle/joint aches, nausea or rash.
- A person can become more unwell around the time the fever starts to settle, so a lower temperature does not always mean danger has passed.
- Avoid assuming every fever is dengue; testing and clinical assessment matter when dengue is suspected.
Why this deserves attention
Dengue can begin like many viral illnesses. Learn the typical pattern, why hydration and medical review matter, and which bleeding or shock symptoms need urgent care.
The same symptom can have several causes. Useful clues include how quickly it changed, how severe it is, what comes with it, personal risk factors and whether it is clearly different from your normal baseline.
What to observe
Keep track of fever duration, fluid intake, urine output, vomiting, abdominal pain, unusual bleeding and how alert the person feels.
Write down when symptoms happen, how long they last, triggers, changes in normal function and medicines or supplements already taken. A short record often makes a consultation more useful.
Sensible next steps
Seek medical assessment if dengue is possible. Rest and hydration are important, but medicines should be chosen carefully and according to professional advice.
Medical assessment and where TCM fits
There is no simple home method that reliably determines severity. Blood counts and clinical monitoring may be needed, especially when symptoms evolve.
TCM should not delay dengue testing or medical monitoring. Herbs and supplements should be disclosed because dehydration, liver involvement or bleeding risk may alter what is safe.
TCM and conventional care can sometimes complement each other, but acute red flags, conditions needing imaging or blood tests, and diseases with established evidence-based treatment require diagnosis and safety to come first.
When not to wait
Severe abdominal pain, repeated vomiting, bleeding, marked drowsiness/restlessness, fainting, cold clammy skin or difficulty breathing needs urgent assessment.
