What is Bronchitis?

Bronchitis refers to an inflammation of the bronchial tubes that carry down to your lungs and back. Depending on the severity of the inflammation, a person suffering from bronchitis may experience a sore throat and/or cough, which is often accompanied by thick, sometimes yellow or green mucus. Although the symptoms are generally the same for both, bronchitis is classified as either acute or chronic depending on the cause and how long the symptoms last.
