Skin rashes can be described as bumps on the body that usually changes the feel and appearance of the skin in a certain area. Outbreaks can be either widespread or confined to a particular area, and they affect different skin types.
Various factors can cause rashes for example; allergic reactions to some types of food, chemicals, anxiety, or other infections. When antigens affect the outer body through lymphocytes, they activate these lymphocytes which produce chemicals that may cause rashes on the skin. For instance, when a person is allergic to a particular medicine, the reaction will take place in the lymph glands and on the surface. Also, viral infections cause rashes because the viral particles will react with the top layer of the skin or epidermis. Some individuals are prone to have allergic rashes while other’s body system is immune to them.
Allergic rashes can affect anywhere on the outer body. Usually, these rashes occur in the area which directly comes into contact with an allergen. The reaction severity depends on the person’s level of sensitivity to the allergen. A person’s skin acts as a natural barrier which protects the internal organs as it is our first line of defense. Mostly, allergens are proteins in nature that are presented to the defense cells of the body, known as lymphocytes. The cells then release some specific chemicals which result in an allergic reaction on the outer body that manifests as different types of rashes.
Some of the common types of skin rashes include:
Eczema or Atopic Dermatitis

It is essential to know that, rashes are as a result of a reaction between allergens and the first skin of the body, and if this is not taken care of, the entire body will go into a shock-like condition as it reacts with the allergens. If you have rashes due to allergy which doesn’t scratch but only makes the symptom worse, you can apply some ice on the affected area which will decrease the blood supply to the region hence decreasing the lymphocytes which in turn reduce the severity of the symptom.
