Often, non-allergic rhinitis presents with inflammation of the nasal mucous membranes, along with its associated indications such as a sensation of having a stuffy nose. However, in some cases, there is an absence of any identifiable inflammation. Symptoms such as itching in the eyes or nose are typically absent because these are associated with allergic reaction. Common signs of non-allergic rhinitis include:
- Nasal congestion.
- A runny nose.
- Mucus running down the back of the throat. This is known as postnasal drip.
- A headache.
- Enlargement of tonsils and adenoid.
- Difficulty in breathing.
- Impairment of the sense of smell.
