From 7 days my mom (48) is suffering from dry cough. Consulted to doctor and taken medicine but after that more reaction has happen it continues coughing and she also not had a good sleep due to that, and even she has become dull and weak. And the taste of mouth has changed as she told me. So request you to revert as soon as possible with good medicine (note: this type of cough happen before also where one doctor consulted corex from that she felt good and cough free.
