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.
Causes Of Wheezing. Often times, wheezing is associated with obstruction and problems in the smaller bronchioles located deep inside the lung rather than larger airways, though the latter is possible as well. It is commonly associated with asthma, which is characterized by thickening of the lining of the airways and development of thick mucus.
