Known simply as a skin rash, it is generally an inflammation of the skin.
It results in changes in the color and texture of the affected area. The skin or body rash could be the effect of irritation, illness, or an allergic reaction . Allergies can be from food, chemicals, plants, animals, insects, or other environmental factors.
This type of skin rash could affect the whole body or be in a specific area. Rashes on the skin on the back are called back rashes.
Skin rashes generally explain some disorders in the human system. These disorders are usually the cause of the formation of rashes on the skin of any person.
There are several reasons that could cause a skin rash. The following are some of the common causes of skin rashes.
The rashes are often caused by anxiety , allergy, or other infections. Numerous antigens affect the skin through lymphocytes. If these lymphocytes are activated by these antigens, they produce chemicals that can cause skin rashes.
For example, when we are allergic to some medicine, the reaction takes place in the skin and also in the lymphatic glands. Viral infections also cause rashes as the viral particles react with the epidermis or top layer of the skin.
Even though the rash is simply recognized, all rashes are not the same. The eruptions vary in their appearance, time, location or distribution, and duration. These rash symptoms could appear individually or in combination, depending on the cause of the rash.
In general, rashes can be described as:
- Macular : flat, red spots.
