Unless there are recurring problems with hives, there is no need to worry about hives. Hives is medically known as urticaria.

Hives are formed by histamines and other compounds released from mast cells.

These histamines, which are released from the mast cells, cause the leaking of the fluid from the blood vessels.

This leakage leads to swelling of the skin. Hives can form anywhere in the body, but usually in the palms and soles of the feet.

There are different types of hives, which include:

Acute:Acute urticaria (hives) is sometimes due to allergies. They generally show up in a few minutes after exposure to any allergen and lasts for a few hours to few weeks.

The common causes of acute urticaria include consumption of shellfish, eggs, fish, nuts, dye, derivatives of acids, etc., and medicines such as Amaryl, aspirin, penicillin, sulfonamides, etc. Bee stings can also cause hives.

Chronic: Chronic urticaria mostly is due to autoimmune disease or related to other autoimmune conditions such as thyroid disease.

When the hives persist for more than six weeks, then it is considered to be chronic urticaria. In some severe chronic cases of hives, the reaction lasts almost twenty years. Visually, there will be no difference between acute and chronic urticaria. Depending on the length of the episode, it can be referred as acute or chronic.

Aquagenic (reaction to water), cholinergic (reaction to body heat), dermatographic (reaction when the skin is scratched), vibration (reaction to vibration), heat, cold, adrenergic (reaction to adrenaline and non-adrenaline), etc are some of the physical urticaria symptoms.
