What is Skin Rash

A rash is an eruption that occurs on the skin. The rash usually appears in a cluster of eruptions that may materialize all over the body or be concentrated in one particular part of the body. The onset of skin allergy rashes are usually accompanied by one or more of the following: a change in skin color (the rash affected area tends to turn red), itching, swelling, and a burning sensation.

Causes of Skin Allergy Rash

Allergies and skin rashes go hand in hand. They are the most common cause of a rash. Skin allergy rashes occur when the body’s immune system reacts negatively to an otherwise harmful environmental agent. Other causes of skin allergy rashes include contact with harsh chemicals, fungal or viral infections, or a genetic disorder.

Eczema – Eczema refers to a range of skin conditions that cause skin inflammation. The most common type of eczema is atopic dermatitis. Eczema is not a dangerous condition. However the symptoms—rash and swelling—can cause a great amount of irritation and sometimes pain. An episode of eczema can be a result of an underlying illness, allergies, exposure to harsh environmental agents, or genetic makeup.

Contact Dermatitis – Contact Dermatitis is a form of eczema. It is a rash allergy that breaks out when the skin is exposed to external allergens and irritants. The symptoms of contact dermatitis include red rashes, blisters, dry patches, and a burning sensation. Depending on the severity of the rash, the condition can be mild or painful. Common irritants include harsh detergents, chemicals, metals, plants (like poison ivy), and medications. Common allergens include pollen and foods.

Hives – Hives are a common skin condition characterized by red, itchy welts erupting across the body. Also known as urticaria, hives appear as raised red welts. They either show up isolated or in clusters that tend to bind together into a bigger welt. Hives are caused when the small blood vessels leak fluid. This fluid collects under the skin forming angry red patches and welts on the skin. Hives can be very uncomfortable, with the itch ranging from mild to painful. Hives are usually triggered by allergic reactions to foods, aggressive medicines, exposure to extreme temperatures, stress, and viral infections. The symptoms last up to six weeks. If the rash persists even after six weeks, it is referred to as chronic hives.
