A rash is a change of the skin which affects its color, appearance, or texture.
A rash may be localized in one part of the body, or affect all the skin. Rashes may cause the skin to change color, itch, become warm, bumpy, chapped, dry, cracked or blistered, swell, and may be painful.
The causes, and therefore treatments for rashes, vary widely. Diagnosis must take into account such things as the appearance of the rash, other symptoms, what the patient may have been exposed to, occupation, and occurrence in family members.Rash can last 5 to 20 days, the diagnosis may confirm any number of conditions.
The presence of a rash may aid diagnosis; associated signs and symptoms are diagnostic of certain diseases. For example, the rash in measles is an erythematous, morbilliform, maculopapular rash that begins a few days after the fever starts. It classically starts at the head, and spreads downwards. Here are some common skin rashes:

Heat rash (miliaria): This skin eruption is caused by the occlusion of sweat ducts during hot, humid weather. It can occur at any age but is most common in infants who are kept too warm. Heat rash looks like a red cluster of pimples or small blisters. It is more likely to occur on the neck and upper chest, in the groin, under the breasts, and in elbow creases. Treatment involves moving the individual to a cooler environment.

Hives: These red itchy bumps come on very quickly and then resolve in about eight hours. They tend to recur frequently.

Viral rash: While viral infections of the skin itself, like herpes or shingles (a cousin of chickenpox), are mostly localized to one part of the body, viral rashes are more often symmetrical and everywhere. Patients with such rashes may or may not have other viral symptoms like coughing, sneezing, or stomach upset (nausea). Viral rashes usually last a few days to two weeks and go way on their own. Treatment is directed at relief of itch, if there is any.

Drug eruptions: Certain drugs can produce skin rash as an unwanted side effect. The common appearance is similar to rashes produced by certain common viral infections. On the other hand, drugs may produce a wide variety of other types of rashes.

Nummular eczema: This is a weepy, oozy dermatitis that tends to occur as coin-shaped plaques in the wintertime and is associated with very dry skin.

Psoriasis: This bumpy scaling eruption never weeps or oozes and tends to occur on the scalp, elbows, and knees. It leads to silvery flakes of skin that scale and fall off.

Stasis dermatitis: This is a weepy, oozy dermatitis that occurs on the lower legs of individual who have chronic swelling because of poor circulation in veins.

Diaper rash: This is a common type of contact dermatitis that occurs in most infants who wear diapers when feces and urine are in contact with skin for too long.

Contact dermatitis: Contact dermatitis is a rash that is brought on either by contact with a specific chemical to which the patient is uniquely allergic or with a substance that directly irritates the skin. Some chemicals are both irritants and allergens. This rash is also occasionally weepy and oozy and affects the parts of the skin which have come in direct contact with the offending substance. Common examples of contact dermatitis caused by allergy are poison ivy or poison oak (same chemical, different plant) and reactions to costume jewelry containing nickel

Atopic dermatitis: Atopic dermatitis, often called eczema, is a common disorder of childhood which produces red itchy, weeping rashes on the inner aspects of the elbows and in back of the knees as well as the cheeks, neck, wrists, and ankles. It is commonly found in patients who also have asthma and hay fever.

Seborrheic dermatitis: Seborrheic dermatitis is the single most common rash affecting adults. It produces a red scaling eruption that characteristically affects the scalp, forehead, brows, cheeks, and external ears.

Diagnosis of rashes:
The term rash has no precise meaning but often is used to refer to a wide variety of red skin eruptions. A rash is any inflammatory condition of the skin. Dermatologists have developed various terms to describe skin rashes. The first requirement is to identify a primary, most frequent feature. The configuration of the rash is then described using adjectives such as "circular," "ring-shaped," "linear," and "snake-like." Other characteristics of the rash that are noted include density, color, size, consistency, tenderness, shape, and even temperature. Finally, the distribution of the rash on the body can be very useful in diagnosis since many skin diseases have a predilection to appear in certain body areas. Although certain findings may be a very dramatic component of the skin disorder, they may be of limited value in producing an accurate diagnosis. These include findings such as ulcers, scaling, and scabbing. Using this framework, it is often possible to develop a small listing of the possible diseases to be considered.
