Recurrent dry cough needs to be evaluated to find out the cause for it whether it's infective or allergic..
Management depends on it..For that detailed Medical history is required.
As of now general advice would be to continue gargling..it may relief your throat. You can also take steam inhalation, it will help in improving your upper airway problems.
