Yellow water flowing from the ear allergy is mostly eczema of the external auditory canal, which is related to inflammatory exudation of the external auditory canal after contact with allergens.
Eczema of the external auditory canal is usually associated with allergic factors, often caused by contact with allergic substances such as cosmetics, soap, milk, eggs, seafood, drugs and other allergens. The main symptoms are itching of the skin of the external auditory canal and yellowish water, which is often characterized by a yellowish watery discharge.
The yellow water is due to the dilation and congestion of blood vessels under the skin of the ear canal, resulting in dermal edema and perivascular inflammatory reaction, leading to the exudation and infiltration of eosinophils and lymphocytes, which can also be manifested as tissue degeneration and necrosis. Allergens should be kept away from in daily life, and drugs such as loratadine can be taken under the guidance of a doctor in the acute stage.
It is recommended that patients are advised to check their condition in time and develop appropriate treatment programs under the guidance of physicians.
