I am having cough which came after cold. It is not going away since 2 months. No phlegm. Only dry cough which comes now and then. I have consulted doctor and he gave me medicines for gerd. 1st time he gave me rabiwok dsr for day time and nexpro fast for night along with gaviscon syrup for 3 times after meals. The cough had gone after that. After 2 months again I met with cold. After cold again cough came and it doesn't going away. After that another time he gave me hp kit for 14 days along with sucrafil o syrup and tossex syrup. But cough is not going away. There is no other symptoms except dry cough. If it is gerd why does cough only comes whenever I met with cold? Also he said my lungs are perfect with having 98% oxygen saturation. What can I do now? Please help. There is always feels like irritation in my that. Please help.
