When should I see a doctor about the flu?

Answer by:

If your symptoms aren't getting better after a week or if you have fever for more than 3 days, see your doctor.

Also, these symptoms are signs that flu may have developed into something serious like pneumonia. See a doctor if you have any of these symptoms:

  • Hard to breathe
  • Fever that lasts
  • Persistent vomiting or can't keep fluids down
  • Cough, congestion, and headaches that won't go away
  • Severe dizziness

Is it a cold or the flu?

Test your knowledge.
