Symptom Guidance
This is deliberately NOT a symptom checker that names a disease. Those tools are wrong often enough to be dangerous, and a list of frightening possibilities helps nobody. What is genuinely useful — and what this does — is help you judge how urgent something is, what to tell the doctor, and which symptoms must never be waited on.

This cannot diagnose you and does not try to. If a symptom is severe, sudden, or getting rapidly worse, seek medical help now rather than reading further.
Numbers are listed for 55 countries and can change — if your country is not here, or you are not sure, 112 reaches emergency services across the European Union and works from a mobile in much of the world. Do not drive yourself.
Three questions that decide urgency
Before anything else, these three tell you more than any symptom list.
- 1How fast did it come on?Sudden — over seconds or minutes — is the single most worrying feature of almost any symptom. A headache that peaks in seconds, breathlessness that arrives abruptly, weakness that appears at once: these need emergency assessment regardless of severity.
- 2Is it getting worse, and how fast?Something steadily worsening over hours needs attention today. Something stable for weeks can usually wait for a routine appointment.
- 3Is anything else happening with it?Chest pain alone is one thing; chest pain with sweating and breathlessness is another entirely. Fever alone is common; fever with a stiff neck or a rash that does not fade is an emergency.
Symptoms that always mean emergency help
- Chest pain or pressure lasting more than a few minutes, especially with sweating, nausea or breathlessness.
- Sudden weakness, numbness, difficulty speaking, or loss of vision — use the FAST test.
- Severe difficulty breathing, or breathlessness at rest.
- A sudden severe headache that peaks within seconds.
- Fainting or collapse, or a first-ever fit.
- Uncontrollable bleeding; vomiting blood; black tarry stools.
- Swelling of the lips, tongue or throat with difficulty breathing.
- Severe abdominal pain with a rigid abdomen.
- Any thought of ending your life.
Working out where to go
| If this is true | Where to go | How soon |
|---|---|---|
| Any red-flag symptom above | Emergency department, by ambulance | Now — call emergency help |
| Severe pain, high fever with confusion, dehydration you cannot correct | Emergency department | Now |
| Fever more than three days, persistent vomiting, a wound looking infected, a flare of a known condition | Your doctor, or an urgent care clinic | Today or tomorrow |
| A cough over three weeks, unexplained weight loss, a lump, a mole that has changed, blood anywhere it should not be | Your doctor | Within a few days — do not put it off |
| A long-standing problem you want reviewed; a medication question; a check-up | Your doctor, or an online consultation | A routine appointment |
Make the appointment count
Most consultations are short. What you bring to them decides how much they are worth.
- When it started, and what you were doing at the time.
- Whether it is constant or comes and goes, and what makes it better or worse.
- How severe, in a way that is comparable — what it stops you doing is more useful than a number out of ten.
- Everything you take, INCLUDING over-the-counter medicines, ayurvedic and homeopathic preparations, and supplements. Bring the boxes if you can.
- Your allergies, and what actually happened when you reacted.
- Any previous test results and discharge summaries you have.
- The ONE question you most want answered — ask it first, not as you are leaving.
Why we do not name diseases here
Symptom checkers that output a diagnosis get it wrong a great deal of the time, and they fail in both directions. They frighten people with rare and serious possibilities for ordinary symptoms, and they reassure people whose serious illness happens to present mildly. Neither error is acceptable on a medical site.
What a website genuinely can do is help you judge urgency, prepare properly and recognise the things that must not wait. That is what this page does. For anything beyond it, the Multiverse offers teleconsultation and home visits with real doctors who can examine you, take a history and be accountable for what they conclude.
This is general health information for education, not medical advice, and not a diagnosis. It cannot see you, your history, your allergies or your medicines. Never use it to start, stop or change a treatment, and never let it delay you seeking care. If you are worried about symptoms, speak to a qualified doctor; if they are severe or sudden, seek emergency help.
Where this comes from: Triage guidance consolidated from widely published emergency and primary-care advice. Urgency categories only; no diagnoses.
Where this is written from: This site is written from Indian clinical practice. Drug availability and brand names, vaccination schedules, national health programmes and some reference cut-offs differ between countries — a schedule or a threshold that is standard here may not be standard where you are. If you are reading outside India, check anything on this page against your own country’s guidance before you act on it.
