When to See a Doctor vs. Try Self-Care: A Practical Guide
Most everyday symptoms resolve on their own — but some need urgent attention. Use this framework to decide what to do next.

The three-question rule
Before deciding between rest at home or a trip to the clinic, ask yourself three questions: 1. Is anything in the "red flag" category? Severe chest pain, sudden weakness on one side, difficulty breathing at rest, confusion, persistent vomiting, sudden severe headache, signs of anaphylaxis (swelling of lips/tongue, difficulty breathing). Any "yes" means emergency services, not self-care. 2. How long has it been there? Most viral illnesses peak around day 3 and improve by day 7. A symptom that's getting worse on day 4 or still severe on day 10 deserves a closer look. 3. Is it interfering with eating, sleeping, or normal function? Symptoms that prevent you from drinking fluids, sleeping, or doing basic tasks usually warrant medical attention regardless of duration.
Common symptoms and what they typically mean
Sore throat without fever: Usually viral. Hydration, lozenges, warm salt water gargles. See a doctor if you can't swallow saliva, develop a high fever, or symptoms persist beyond 7-10 days.
Headache: The most common cause is tension or dehydration. Drink water, rest, try ibuprofen if appropriate. Seek emergency care for a "thunderclap" headache (worst of your life, sudden onset) or headache with fever, stiff neck, vision changes, or neurological symptoms.
Stomach pain: Most settles within 24-48 hours. The location matters: pain starting around the belly button and migrating to the lower right could be appendicitis — a surgical emergency. Severe pain, fever, vomiting, or pain that wakes you from sleep needs prompt evaluation.
Cough: Acute (under 3 weeks) is usually viral. Chronic cough deserves investigation. Cough with shortness of breath, chest pain, blood-tinged sputum, or fever above 39°C should be assessed by a clinician.
Rashes: Most are harmless contact reactions. A rash with fever, that doesn't blanch when pressed, or that spreads rapidly should be evaluated urgently.
How AI triage fits in
A tool like MedSage is most useful in the gray zone — when you suspect something might need attention but you're not sure. By describing your symptoms in detail, you get a structured suggestion of likely causes, an urgency level, and a list of warning signs to watch for.
The goal is not to replace your GP. The goal is to help you make a calmer, better-informed decision about whether to wait, call, or go in — and to arrive at the consultation prepared.
