 | | For example, a cough can be a symptom of asthma, acid reflux into the esophagus (gastroesophageal reflux disease, or GERD), side effects of medications, sinusitis, postnasal drip, bronchitis, cigarette smoking, pneumonia, tuberculosis, hypersensitivity pneumonia (inflammation of the lung from exposure to certain environmental chemicals), and even lung cancer. |
