Is it a sinus infection, cold, or the flu?

Differentiating between a cold, flu, and sinus infection involves looking at symptom severity and specific signs: colds are usually mild with sneezing/runny nose, flu hits hard with fever/body aches/fatigue, while sinus infections focus on facial pain/pressure, thick colored mucus, and potentially lingering symptoms after a cold, often worsening when bending over. A cold is short, flu is intense and brief, and sinus issues (often secondary) can persist longer and involve localized facial pain and yellow/green discharge.

How do you tell if you have a flu or sinus infection?

The flu hits hard and fast with fever, full-body aches, and intense fatigue, while a sinus infection develops more slowly, focusing symptoms on the face with pressure, localized pain, and thick, colored nasal discharge, often following a cold. Key differences: Flu brings whole-body symptoms and high fever; sinus issues cause facial pain, congestion, and thick mucus, often without high fever, but can linger.

Sinus infection mucus is typically thick, yellow or green, indicating your immune system is fighting an infection, with the color coming from dead white blood cells.

If green mucus persists for over 10 days or is accompanied by severe symptoms, see a doctor as it could signal a bacterial infection needing treatment.
