If you have chronic obstructive pulmonary disease (COPD), it is fairly common to suffer from chest pain or chest tightness especially in the morning. Increased amount of mucus consolidated in the lungs causes chest tightness. Blockage of the air passages can also contribute to cause this worrisome symptom. Chest tightness can make it difficult for the patient to expire and inspire air. Chest tightness can often be treated with medication and aerosol therapy. Albuterol is a great and quick relief method as it opens the blocked airways.
