The symptoms of wheezing include a musical or whistling sound and labored breathing, particularly when exhaling; sometimes they're accompanied by a feeling of tightening in the chest. You can hear wheezing more loudly if you plug your ears and exhale rapidly, or by using a stethoscope held at the neck or over the lungs.
Other infections. An infection anywhere in the respiratory tract may trigger wheezing. For example, acute bronchitis (infection of the bronchi) is common in adults and may cause some wheezing in addition to other symptoms. A viral respiratory infection is a common cause in young children.
