Okay...1. since you respond to Laevocetirizine, an antihistamine, you obviously have Allergic Rhinitis, and as it is regular in its recurrence, it is a Perennial Persistent type. Next step: what are you allergic to? Can it be avoided? How to manage this?
For that you will need to meet me at my clinic, where I will examine you and those CT scan images thoroughly. Then I will put you on some non-systemic medications for 3 weeks instead of Laevocetirizine tablets so that you can undergo skin-prick tests to identify the allergens that your immune system has been sensitised to. Then I will advise you appropriately on what to do next.
