👉 Periencephalitis is a condition that occurs when the lining of the nasal cavity (perion) becomes inflamed, which can lead to symptoms such as pain or discomfort in the nose. It's usually caused by an infection or inflammation of the nasal passages, but it can also be a sign of other underlying conditions like allergies, asthma, or even chronic sinusitis. The exact cause is often difficult to determine and varies from person to person.
