Hives are a raised, itchy, red rash caused by tiny amounts of fluid that leaks from the blood vessels just under the skin’s surface. It may appear on one part of the body and be just a few millimetres in size, or be spread across larger areas.
There’s two main categories of hives:
It’s estimated that one in five people will be affected by acute urticaria at some point in their lives, whereas chronic urticaria will only affect about one in 100.See a Doctor About Hives
The condition consists of spots or patches of raised red or white skin, which usually clear away in a few hours and are then replaced by fresh patches. It typically occurs with swelling in other areas of the body (usually the hands and feet) and will be itchy, painful or cause a burning sensation.
Most cases will involve symptoms being present for around eight to 12 hours and these will rarely continue for more than 24 hours. In rarer cases, problems will continue for quite a few days, and even several months.
Urticaria has a tendency to flare up because of triggers, such as heat, exercise and stress. Symptoms may also reoccur frequently, unpredictably, and will sometimes last for months or years.
You should seek emergency care if you have any of the following symptoms, since these can indicate the presence of a more serious condition:
Acute urticaria: This won’t usually require treatment due to the condition being mild and relatively short-lived. If the condition persists or slightly worsens, antihistamines/corticosteroids may be prescribed to manage symptoms.
Chronic urticaria: For those suffering from long-term bouts of hives, medication may be prescribed such as antihistamines, menthol cream (to reduce itching) and corticosteroids. There are, however, other types of treatment available that can help with managing the condition:
