Sinus Infection or Cold: When to Seek Care
Colds and sinus infections can both cause congestion, facial pressure, cough, and nasal discharge. Most sinus infections are viral and do not need antibiotics; a clinician looks at the duration, severity, progression, and examination rather than mucus color alone.
Key answer
The short version
Colds and sinus infections can both cause congestion, facial pressure, cough, and nasal discharge. Most sinus infections are viral and do not need antibiotics; a clinician looks at the duration, severity, progression, and examination rather than mucus color alone.
Time course is useful evidence
CDC advises medical evaluation for severe symptoms, symptoms lasting more than 10 days without improvement, a fever lasting more than three to four days, or symptoms that improve then worsen.
Antibiotics have a narrow role
They do not treat viral infections and can cause side effects. A same-day visit can help determine whether supportive care, watchful waiting, testing, or treatment is appropriate.
Clinical perspective
How to think about this
Good same-day care is not about labeling every symptom; it is about matching the urgency and setting to the problem. A careful history, examination, and targeted testing can prevent both dangerous delay and unnecessary treatment.
Questions worth bringing to a visit
- Is this appropriate for a same-day office visit or emergency care?
- What result would change treatment today?
- What changes should prompt me to seek help sooner?
