How does allergies and cough occur?

When you are allergic to some substance it causes your nose membranes to become inflamed and produce phlegm. When this phlegm drains from your nose to the back of your throat it will cause irritation to the throat, which produces cough. The draining of phlegm form the back of the nose into the throat is referred to as post nasal drip. Therefore, the cough occurs because the throat is congested and you need to clear the phlegm out of it. The post nasal drip can be due to rhinitis or sinusitis.

Rhinitis: inflammation in the nasal passages
Sinusitis: inflammation in the nasal cavities
