They tend to change their size and shape. They might come together to form a larger area called plaque.

It is known that they reappear after disappearing in a different formation. Allergies are a major cause of hives.

However, there are other reasons too, including blood transfusions, food, infections, insect bites, stings, clothes, medications, climate, or internal disease.

They are classified as acute as well as chronic conditions. These can be mild or severe.

In many cases, they disappear after a while. Some home remedies are helpful too.

However, stretching, physical movement, alcohol, and stress can make the condition worse. Antihistamine is a popular recommendation for the treatment of hives.

What is Rash?

irritating substances, medications, plants, psoriasis, or sun exposure.

These can be developed out of a sudden or developed over a period of time of several days.

The treatments given to the patients are based on the type of rash, acute (less than six weeks), chronic (more than six weeks), and cause of the rash.

Basic treatments include moisturizing lotions and creams. Treatments vary, depending on what caused the rash in the first place

but may include moisturizers, corticosteroid creams- for redness and swelling, and antihistamines- for redness and itching.
