During a cold the mucous membranes in the nasal region swell up and produce a secretion. You therefore either get a blocked or runny nose. If the infection spreads to the air-filled cavities in the jaw, nose or forehead region, the sinuses become inflamed, i.e. sinusitis develops.
The swollen mucous membranes obstruct the necessary drainage of the secretion.
This frequently results in:
- Pressure pain
- Strong sensitivity in these areas
- Impeded nasal breathing
- Headaches especially when bending over
