With sinus symptoms, the key question is whether antibiotics are likely to help.
Blocked nose, facial pressure, mucus and cheek pain are often part of an ordinary viral respiratory infection. Antibiotics do not open a blocked nose or shorten a viral cold. The assessment should focus on whether the overall picture fits bacterial sinusitis.
symptoms have lasted about 10 days without clear improvement
symptoms worsen again after initially improving
pain or pressure is clearly one-sided, especially with cheek or tooth pain
fever, purulent discharge or reduced general condition make bacterial disease more likely
When do antibiotics usually not help?
symptoms have lasted only a few days and fit an ordinary cold
the main problem is congestion, pressure or mucus without other evidence of bacterial disease
symptoms are already improving
the likely cause is viral infection, allergic rhinitis or irritation-related rhinitis
What is assessed during the appointment?
The visit focuses on duration, severity, one-sided symptoms, general condition, fever, clinical findings and whether tests or onward assessment are needed. Often the best treatment is symptomatic care and clear safety-netting. If bacterial disease is likely, antibiotics may be justified.
When is urgent assessment needed?
Eyelid or facial swelling, visual symptoms, severe headache, confusion, neck stiffness, high fever or clearly worsening general condition require more urgent assessment.
Clinical decision-making
The antibiotic decision is not based on the colour of mucus alone.
With sinus symptoms, I mainly assess duration, severity, one-sidedness, general condition and whether symptoms worsened again after first improving. Coloured mucus or nasal blockage alone does not make antibiotics useful.
