Thanks for writing your query.
It seems that you are suffering from Allergic Rhinitis
, an allergic condition.
You should identify the allergen and avoid it.
Taking antiallergic medicines like Fenofexadine
120 mg once a day, will be helpful. Take medicines under medical supervision only.
Also get your blood tested for Complete Blood Count
including Absolute Eosinophill Count.
Make it a habit of washing your hands with soap and water before and after meals. This will decrease the frequency and duration of infection. Also eat fresh fruits and vegetables. This increases your immunity to fight infections.
If the problem persists, get yourself examined by a Physician.
I hope this is helpful to you.
