The decision of whether to see a doctor or manage symptoms at home is one most adults face dozens of times a year. Getting it right requires a blend of symptom knowledge, risk awareness and honesty with yourself about whether your symptoms are improving.
Symptoms that generally manage well at home
- Common cold — runny nose, sore throat, mild fever; rest, hydration and paracetamol; most resolve within 7–10 days
- Mild gastroenteritis — vomiting and diarrhoea without blood or severe dehydration; clear fluids and rest
- Minor cuts and abrasions — clean, cover, monitor for signs of infection
- Mild allergic reactions — hives or mild itching; antihistamines; monitor for worsening
- Muscle strains and minor sprains — RICE protocol (rest, ice, compression, elevation)
- Indigestion and heartburn — dietary changes and OTC antacids for occasional episodes
Symptoms that need prompt medical attention
- Chest pain — especially with breathlessness, sweating or pain radiating to the arm or jaw
- Sudden severe headache — 'the worst headache of my life'; may indicate subarachnoid haemorrhage
- Difficulty breathing at rest — not explained by anxiety or known asthma
- High fever (above 39°C) lasting more than 3 days, or any fever with a rash
- Severe abdominal pain, particularly if one-sided or associated with vomiting
- Blood in urine, stool or vomit — unless you know the cause
- Symptoms that seem to be getting worse rather than better after 48–72 hours of home treatment
The middle ground
Between 'home treatment is fine' and 'call an ambulance' lies a large space where the right answer is often 'see your GP within 24–48 hours'. A useful rule: if you're genuinely unsure whether something is serious, phone your GP's advice line or a nurse helpline. They can triage your symptoms and advise whether you need to be seen today, soon or can wait.
