I am 36 years old. I have had a dry cough for 2 months (with sore throat).

The most likely reason for your symptoms is a mild but persistent infection in your upper respiratory tract.

However, as the problem has persisted for such a long time, you should really see your doctor to exclude a more serious health problem. If your doctor finds nothing sinister, you may wish to try Bronchosan Pine Cough Syrup for dry coughs.
