1-2 Weeks Most viral infections resolve on their own within this timeframe. Focus on rest, hydration, and over-the-counter remedies for symptom relief.
Over 10 Days If symptoms do not improve after about 10 days, it could indicate a secondary infection like a sinus infection. Consult a doctor to determine if antibiotics or other treatments are necessary.

  • Prolonged Symptoms: If symptoms persist beyond two weeks.
  • Severe Symptoms: When symptoms are intense or significantly impact daily life.
  • Lack of Improvement: If symptoms do not show any signs of improvement after about 10 days.
