hi,thanks for query.This allergic rhinitis
only.Some allergen like dust,smoke or strong smell acts as triggers and that leads to allergic reaction
which can lead to series of events.If you can find one,please avoid allergen is the best treatment,in other case you can go allergy
testing and try to find a cause.Some anti allergic immunoglobin injections gives relief for long term,please discuss this with your doctor.
wishing good health.
