Symptoms of dermatitis and eczema, distinguishing between acute and chronic

Eczema can cause itching symptoms. The most common types of eczema are dermatitis eczema, which can be divided into acute and chronic types. Dermatitis eczema is very prone to recurrence. To treat eczema, you should choose the right medicine and take good care of yourself in your life. Don't scratch it with your hands.

1. Symptoms

The diagnosis is relatively easy based mainly on the medical history and clinical manifestations. The rash of acute eczema is polymorphic, symmetrically distributed, and tends to exude; the chronic lesions are lichenified; and the subacute lesions are between the above two. The patient feels severe itching and is prone to relapse. For special types of eczema, attention should be paid to its unique clinical symptoms, and diagnosis is not difficult. Chronic eczema needs to be differentiated from neurodermatitis, in which itching occurs first and then the rash develops. Lichenification is obvious, the lesions are dry, generally without exudation and pigmentation. It often occurs in the neck, sacrum and extensor side of the limbs. It can tolerate a variety of drugs and physical and chemical stimulations.

2. Life Taboos

Avoid scratching

Scratching can cause the skin to be constantly exposed to mechanical stimulation, causing it to thicken and even cause infection. Scratching also has a reinforcing effect. The more the patient scratches, the more itchy it becomes, and the more itchy it becomes, the more he scratches, forming a vicious cycle and prolonging the course of the disease.

Avoid hot water washing

In the acute stage of dermatitis and eczema, due to the dilation of capillaries in the skin, there will be varying degrees of skin redness, swelling, papules, and blisters. Washing or soaking with hot water will increase the redness and swelling, increase the amount of fluid, and worsen the condition. Therefore, patients with dermatitis and eczema should take a warm shower and avoid soaking in hot water or rubbing hard.

Avoid washing with soap

In particular, soaps with high alkalinity are chemical irritants to the skin and can aggravate dermatitis and eczema. If you need to use soap to remove stains, it is best to choose boric acid soap with less irritation.

3. General treatment

At present, Western medicine has no specific treatment for eczema, and most of the treatments are oral antihistamines, such as diphenhydramine, phenergan, chlorpheniramine, cyproheptadine, etc., which can be used alone or in combination, and can also be used with sedatives, vitamin C, etc. The dosage form of topical medication is determined according to the clinical manifestations of skin lesions. If there is obvious redness and swelling, and a lot of exudation, a solution-based cold wet compress should be used. For erythema and papules, lotions, emulsions, mud pastes, oils, etc. can be used; for blisters and erosions, an oil is needed.
