Chronic eczema is a relatively common disease, mainly caused by allergic reactions. In terms of treatment, it is generally not necessary to use injections. The more common approach is the oral administration of anti-allergy medications, combined with the use of topical ointments. The main goal is to control the condition and alleviate symptoms, and it is still difficult to achieve a complete cure at present. It is recommended to conduct an in vitro allergen test to determine the specific types of allergens. In daily life, it is necessary to avoid contact with substances that are likely to cause allergies as much as possible. Most patients will gradually improve after timely treatment, but regular follow-up visits are needed because some patients may experience multiple recurrences of the condition. (Please use specific medications under the guidance of a doctor.)
