How to tell if it's eczema

1Speed ​​of appearance

Eczema usually appears slowly, with a few spots at a time, and does not suddenly appear in a large area. However, prickly heat is just the opposite, appearing in a large area in a short period of time.

Urticaria is an acute onset disease, while the symptoms of eczema are persistent. Once urticaria patients come into contact with allergens, their skin will be allergic and a rash will appear quickly, but it will disappear on its own within 24 hours. Then a new rash will appear on the affected area and disappear again, and the condition will recur.

2. Different appearances

Eczema: At the beginning, the skin becomes red, with needle-sized red papules, miliary rash or ulcers, and then it is accompanied by exudate and may form scabs. After the scab falls off, a red and moist surface is exposed, which is erythema, and it is extremely itchy. After several weeks to months, the edema and erythema begin to subside, the erosion surface disappears, the skin becomes dry, and a few thin crusts or scales appear.

Prickly heat: It is a dense collection of round, pointed, needle-sized papules or papulovesicles with a slight red blush. They often appear one by one and will slightly desquamate after disappearing. In addition, heat rash often appears suddenly and increases rapidly, so we don’t need to be too surprised if we find that our baby has heat rash all over his head or neck when he wakes up.

Patients with urticaria develop irregular, red or white wheals or papules of varying sizes on their skin, which cause temporary itching.

3 Skin changes

Prickly heat is common in hot seasons and will gradually disappear on its own after cooling down. The skin on the affected area of ​​eczema is relatively dry and rough, like a scab, but this is not the case with prickly heat. Eczema is common all year round and is not easy to cure. Urticaria is mainly red and white flat herpes, which often occurs in the spring when people are prone to allergies.
