I am allergic to dermatophagoides farinae and suffer from allergic rhinitis. I should have had it a long time ago. It's serious, but when I have a cold, my nose is blocked, and there are no obvious symptoms at other times.

I don't know whether to take medicine at any time or when my nose is blocked.

Also, my chronic pharyngitis should be caused by this reason. I don't know how to cure it If you know, please come and help me. Thank you.
