Could be asthma...: Usually a cough is due to drainage from the nose into the throat from a cold or allergies. Preventing the post-nasal drainage with saline nasal spray or rinse and clearing the nasal passages frequently can help. Guaifenesin can help loosen secretions. Cough can also be a sign of asthma, or pneumonia. If associated with persistent shortness of breath, have it evaluated by a doctor ASAP.
