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.
A diagnosis of wheezing and its cause can easily be delayed or missed because wheezing may be mild or intermittent and for other reasons. For information on misdiagnosis, refer to misdiagnosis of wheezing.
