Yes, it seems you are suffering from Allergic Rhinitis
Get a total and differential count of blood done, and an X-Ray of Paranasal sinuses
And be on the vigil for things you are allergic to (Oh no, I didn't mean your darling wife...Ha Ha Ha !).
On a serious note, avoid exposure to cold
Drink plenty of water.
Take the reports and consult an ENT Specialist
Taking Montec-LC for long periods of time is not the remedy of your malady.
