It should be chronic rhinitis. I also have this symptom, especially in winter. You can try a massage. My grandmother told me. Press the bridge of the nose under the corner of the eye with your index finger and draw a circle, 50 times clockwise and 50 times counterclockwise. I have an uncle who has lost his sense of taste because of rhinitis. This is the way to cure it.
I wish you a speedy recovery!
