Causes and Remedies for Persistent Dry Cough
A dry cough, also known as persistent dry cough, and productive cough are of two types. A productive cough is usually experienced with phlegm or mucous-whilst coughing and should not be suppressed. Phlegm is the gunk that the body needs to get rid of. Persistent dry cough, on the other hand, usually occurs together with a tickly cough and is usually caused due to allergy or by viral infections.
