J30: Vasomotor and allergic rhinitis
J30.4: Allergic rhinitis, unspecified
The inside of the nose is covered with mucous membrane. The mucous membrane swells up during rhinitis. The mucous membrane then produces more fluid. As a result, the nose runs. Furthermore, it can be more difficult to breathe through the nose and to smell.
Your rhinitis is caused by an allergy. With an allergy, the immune system overreacts to certain substances. Such substances may be harmless substances in the environment, drugs or certain chemicals, for example.
