Vasomotor rhinitis is a term used to describe a condition where the blood vessels in the lining of the nose become inflamed and swollen, leading to symptoms such as nasal congestion and runny nose. There are several other terms used to refer to this condition, including non-allergic rhinitis, non-allergic vasomotor rhinitis, and idiopathic rhinitis. Non-allergic rhinitis is used to describe cases where the condition is not caused by an allergy. Non-allergic vasomotor rhinitis emphasizes the role of blood vessel changes in the condition. Idiopathic rhinitis is used when there is no identifiable cause for the symptoms. Regardless of the terminology used, the symptoms and treatment approaches for the condition remain largely the same.
