Signs and Symptoms of Bronchitis

2. Sore Throat

Most people who develop a cold usually start to develop a cough and sore throat as well.  This is often because the mucus from the runny nose drips into the throat (first the pharynx and then the larynx), and irritates the throat lining.  Also consider that the mucus from the runny nose would contain microbes which can further infect and inflame the throat.  Once the throat is infected and inflamed, it becomes sensitive and sore.  A sore throat is easily triggered to cough, even when there is no phlegm.  However, as a defense mechanism against the inflammation and infection, the throat will also likely produce phlegm, which in itself can block the air passages and also trigger coughing.

A person suffering from bronchitis will often have a cold, sore throat, and cough all together.  Sometimes these signs and symptoms would be accompanied with a low-grade fever.
