Symptoms to act on
- Persistent or progressive blockage of one nostril
- Blood-stained discharge or repeated nosebleeds from the same side
- Cheek numbness or facial swelling, loosening teeth, or suddenly ill-fitting dentures
- Eye symptoms such as bulging, double or reduced vision, redness, or swelling
- Swelling at the inner corner of the eye or persistent watering of one eye
- Severe headache with frontal swelling, confusion, neck stiffness, or any new neurological symptom alongside sinus symptoms
- A persistent foul smell only you can perceive, or persistent one-sided crusting
Important: Severe headache with confusion, neck stiffness, frontal swelling or a new neurological symptom needs emergency assessment—not an outpatient booking.
These symptoms do not prove a serious condition. They are signs that an examination should happen sooner instead of waiting through another course of medication. An ENT assessment may include nasal endoscopy when a closer look is needed.
