Not every symptom needs a clinic visit. But waiting too long can also make things worse. Use this checklist to decide quickly whether to manage at home, book a telemedicine call, or go to a hospital.

Safe to watch at home (24-48 hours)

Mild colds, a single low-grade fever, simple tummy upset, occasional headaches that respond to paracetamol, and small cuts or bruises usually settle with rest, fluids and basic care.

  • Drink plenty of water, especially with fever or diarrhoea
  • Use paracetamol as directed; avoid mixing multiple painkillers
  • Keep a simple symptom diary (when it started, how bad, what helps)

Book a doctor (same week)

Symptoms lasting more than 3-5 days, repeated headaches or stomach pain, ongoing tiredness, a rash that won't go away, or any new lump deserve a proper review — telemedicine is often enough as a first step.

Same-day care

High fever (>38.5°C) lasting more than 48 hours, painful urination, ear pain in a child, vomiting that won't stop, or worsening cough should be seen the same day. A home visit or clinic appointment is appropriate.
