My rhinitis has been going on for several years, and I'm usually fine. When the weather is cold, my nose keeps running and stuffy.

Nasal congestion and runny nose are the main symptoms of allergic rhinitis. Nasal congestion usually gets worse when you sleep at night. Breathe through the mouth when the nasal congestion is uncomfortable, and some have alternating nasal congestion. If both sides are blocked, the condition will get worse. Some are simple nasal congestion, some will sneeze continuously in cold air, clear their noses, some have itchy nose and eyes, cough, phlegm or asthma. After a long time, it will also lead to loss of sense of smell. Early detection of allergens, desensitization and complete elimination of allergic inflammation in the upper respiratory tract can still be cured.

Regarding the treatment of nasal congestion and allergic rhinitis, you should go to the local allergy center. First, find out allergens for prevention and desensitization treatment, including dust mites, pollen, chemical odors and even food allergies. You can look at this allergy website: "China Allergy and Asthma Network", which has columns on allergic rhinitis and allergic rhinitis asthma syndrome. It will be very rewarding after reading it.
