What are hives on the skin?

Skin rashes in children

The hives on the skin are one of the visible symptoms that denote the appearance of some type of disease. They are an irritation of the skin, which can appear with swelling, reddish color, peeling, and even with the opening of a bleeding wound in the most serious cases.

They can be of small size, or also extend so much that they occupy a large amount of skin. The hives in the body can also spread rapidly and disappear spontaneously, or appear very slowly as part of a chronic disorder.

Hives in children and babies are commonly called urticaria (they also get other names like skin rashes), although as we will see below, childhood urticaria is specifically a type of redness, and not all red welts on the body have to be urticaria. They can also appear due to allergies in children.

Why do hives appear on children’s skin?

Hives on children’s bodies can be caused by different reasons. Among the main causes of hives, the following examples stand out:

  • Insect Bites
  • Infections caused by microorganisms
  • Extreme weather conditions; cold or hot
  • Contact with plants that cause hives in children
  • Contact with chemicals or metals
  • Hives due to allergy to some substance
  • Rash and stress rashes (very common)
  • Sun allergy
  • Food poisoning or medication
  • Reactions to vaccines

Symptoms that accompany hives on the skin

Although not all the welts in the body have to present the same symptoms, the vast majority of them have the same pattern that can be very annoying. Depending on the appearance of the welts on the skin and the other symptoms that accompany them, we can differentiate from what health problem it is, to apply the most appropriate treatment.

For this reason, we must pay close attention to the symptoms that children present with these red spots on the surface of their skin, among which we can highlight:

  • Itching on the body
  • Inflammation more or less marked
  • Stains on the skin reddish
  • Dry, scaly skin
  • Fever
  • Suppuration or rashes on the skin

Types of skin rashes in children

The most frequent skin urticaria in children has nothing to do with skin rashes that usually appear in adults. The most frequent types of urticaria in babies and children are the following:


She is a sick woman caused by a virus, which manifests externally through some welts all over her body. The symptoms that accompany them are fever and itching in the body, and they are precisely the ones that should worry us the most since the welts end up healing themselves.

To differentiate these welts, we must be attentive to their development. They start like small granites that swell and end up exploding, letting a transparent liquid escape. We must wait for the grains to dry, forming a crust to heal.


Dermatitis also causes itching throughout the body, especially in the affected area. It usually presents as a red inflamed area, which flakes and can even form wounds if left untreated.

It appears by rubbing on the upper part of the trunk, on the extremities, the folds, the eyelids and the spaces between the fingers. The most frequent is diaper rash in babies, although they can also be due to being in contact with a substance that damages the skin.


Urticaria is a type of wheal that causes itching throughout the body. They are usually hives due to an allergic reaction, manifested as very large, red and inflamed welts.

Body itching causes

Urticaria throughout the body can spread rapidly and is very bothersome in children.

It can be caused by the reaction to an allergy of some food, medicine, although it is never contagious urticaria between people.

It can also be hives due to heat or extreme cold. It is very common in children and usually resolves itself in a period of 24 to 48 hours.

Milk crust

The milk crust is a type of urticaria on the face that is not accompanied by itching or other symptoms. It is very harmless and very common in babies. It appears along with yellow or white scabs, on the face or on the scalp, with a very greasy appearance

It appears in babies (most times) in their first weeks of life, and disappears alone when the baby is growing. It is not recommended to touch it until it disappears by itself since it does not entail any risk to the baby, beyond the mere aesthetic problem that may arise.


The sudamina or miliaria is a problem of the skin very typical in the babies that can seem hives, but that in fact, they are small granites that have been formed by the obstruction of the sweat in the pore.

They can break the granites giving small blisters, and although sometimes they sting a little, they are not dangerous at all. Mainly they can appear especially in summer when the child is exposed to excessive heat.

These pimples should never be removed in the child, as they could become infected and cause more serious injuries. Over time they end up healing themselves or if not, it is advisable to go to the pediatrician to treat them properly.


In a similar way to the sweets, the fatlings are also granites, but it contains keratin inside. They may have a white dot inside, which could be mistaken for pus or fat, but it has nothing to do with it.

They appear on the face of newborn babies, and they are not annoying, because they do not sting. They end up marching by themselves as the child grows, and it is advisable that they do not touch to eliminate them either.

How to avoid and treat skin rashes

Usually and often, these welts on the skin of the children we have talked about do not need any kind of treatment, since they end up leaving by themselves in a short period of time. In the most serious cases such as urticaria or hives caused by chickenpox, the causes that cause them should be treated.

In any case, it is always advisable to avoid complications, go to the medical center if the child has a high fever, or if he has severe breathing difficulties. If, in addition, it has some dangerous symptoms, we should not hesitate to go to the emergency room.

For the treatment of the pupae that appear along with other skin symptoms, we can use some type of cream to keep the skin healthy and protected. The creams for the baby’s skin are perfect for treating chickenpox pupae and those that appear due to diaper rash.

If we are not sure of the origin of these welts on the skin of the baby, it is best to consult with the pediatrician before applying any type of cream. It should never be done if the welts have opened and they have some wound.

With a good treatment the hives disappear

Now that you know what the rash on the skin of children are and how to treat each type, do not hesitate to get down to work and finish as soon as possible so that children feel more comfortable without those possible symptoms of itching that usually accompany them.
