What are the symptoms of eczematous otitis externa?

Eczema refers to an allergic polymorphic dermatitis caused by the combined action of multiple internal and external factors. It will cause serous exudation, itching, and is prone to recurring. It not only occurs in the external auditory canal but also affects the skin around the ear. It is mostly caused by contact with allergic substances. After suffering from the disease, timely treatment is required. What are the symptoms of eczematous otitis externa? Let me tell you now.

The cause and pathogenesis of eczema are still unclear. It is generally believed to be related to allergic reactions. It may also be related to mental factors, neurological dysfunction, endocrine dysfunction, metabolic disorders, indigestion and other factors. Factors that cause allergic reactions may be food (such as milk, fish, shrimp, seafood, etc.), inhalants (such as pollen, animal fur, paint, chemical gases, etc.), contacts (such as lacquer trees, drugs, cosmetics, fabrics, soaps, chemicals in hearing aid casings, etc.) and other internal factors. Humidity and high temperatures are often triggers. Eczema in the external auditory canal is often caused by contact allergy. The most important allergens are topical medications, such as neomycin sulfate and polymyxin B. Purulent secretions, bacterial or viral infections can also cause external auditory canal eczema.

According to the course of the disease, it is divided into acute eczema, subacute eczema and chronic eczema.

Eczema manifests differently at different stages.

1. Acute eczema

The affected area is extremely itchy, often accompanied by a burning sensation. After digging the ear, yellow watery secretions flow out and form yellow scabs after solidification.

2. Subacute eczema

It is mostly caused by untreated acute eczema, improper treatment or prolonged treatment. The local area is still itchy, with less exudate than acute eczema, but there is crusting and desquamation.

3. Chronic eczema

If acute and subacute eczema recurs or is not cured for a long time, it will become chronic eczema, with severe itching in the external auditory canal, thickening of the skin, and desquamation. External auditory canal eczema may recur.

First, we should try our best to find out the cause of the disease, so we need to have a deep understanding of the patient's work environment, living habits, diet, hobbies, thoughts and emotions, etc.

Second, remove all factors that may induce dermatitis, such as dyes, gasoline, paint, pollen, soap, detergent, etc. Avoid all kinds of external stimulation, such as hot water washing, severe scratching, and try not to wear nylon chemical fiber underwear, but pure cotton white soft underwear.

3. Eat a light diet, avoid spicy foods, and avoid foods that are allergenic and irritating, such as fish, shrimp, strong tea, coffee, and alcohol.

Fourth, patients should avoid mental stress and excessive fatigue. The pace of life, work and study should not be too fast, and they should relax appropriately. Most of the medicines in hospitals are now Western medicines, which also contain hormone ingredients. They are generally not suitable for long-term use. They can be used in small amounts, but not for too long. Traditional Chinese medicine is the first choice for treating eczema and generally does not cause dependence. For treatment, it is recommended to use Chinese medicine, such as Biostime Cream, which is applied 3 to 5 times a day and has a very good effect.

Patients should avoid eating or coming into contact with allergens, treat the disease in a timely manner, and change the bad habit of picking their ears. When washing your hair or swimming, avoid getting water into your ears. Keep your skin dry, wear loose clothes, and avoid eating spicy, raw, cold, or irritating foods. If you find yellow liquid flowing out of your ears, you should go to the hospital in time for cleaning and application of medicine.
