- Congestive heart failure

- Aspiration of food or saliva due to abnormal swallowing

- Ear problems, such as debris in the ear canal

- Eosinophilic bronchitis, an asthma-like problem that does not quickly improve with bronchodilator inhaler treatments

- Bronchiectasis (airway scarring) from a serious prior lung infection

- An abscess in the lung

- Interstitial lung disease
