Explanation:
Detailed explanation-1: -Allergic rhinitis is caused by the immune system reacting to an allergen as if it were harmful. This results in cells releasing a number of chemicals that cause the inside layer of your nose (the mucous membrane) to become swollen and excessive levels of mucus to be produced.
Detailed explanation-2: -In allergic rhinitis, numerous inflammatory cells, including mast cells, CD4-positive T cells, B cells, macrophages, and eosinophils, infiltrate the nasal lining upon exposure to an inciting allergen (most commonly airborne dust mite fecal particles, cockroach residues, animal dander, moulds, and pollens).
