The areas of the skin that are itchy, inflamed, and red are called Hives or welds. About a quarter of the population can weld throughout their lifetime. Hives often appear without warning and can begin at any age.
The word "rash" refers to changes in skin color (such as redness) and / or in texture (such as bumps or swelling). Many rashes cause itching, such as those that usually appear after an allergic reaction; others, on the other hand, cause pain and others do not cause any symptoms.
Angioedema uangioedemana is inflammation that lies beneath the skin surface and fatty tissue. Infected areas can be painful. Angioedema usually occurs on the face, throat, hands, and feet. Inflammation may also occur in the stomach or other areas of the body. Swelling of the throat can be fatal and requires immediate therapy. It is important to understand that 'angioedema' is a medical term that describes inflammation.
It can appear with very different disorders. Angioedema can occur with or without urticaria (urticaria). There are several ways that inflammation can occur. Understanding the underlying mechanism or specific state of inflammation is important to determine the best treatment.
LAS RONCHAS (URTICARIA) and ANGIOEDEMA - symptoms and diagnosis
Hives are itchy and can appear anywhere on the body, including the face, hands, chest, or back. Weldes vary in size: they can measure from a few millimeters to several centimeters. Hives usually disappear within 24 hours, and the skin returns to its normal state without any scars or scratches.
Doctors may have classified your welds based on how much time you have given them. When hives last less than 6 weeks, we talk about acute hives. When hives last more than 6 weeks, we talk about chronic hives. It helps doctors to think about the possible causes of their hives. The reasons for your hives depend on how much time you have.
Chronic urticaria (urticaria for more than 6 weeks) is not dangerous. Hives are sometimes present with angioedema . The cause of chronic urticaria is usually not recognizable. Allergies are not usually the cause of chronic urticaria. This is something that is consistently confirmed by medical authorities and researchers worldwide. The absence of an identifiable trigger can be frustrating for patients.
Drugs can cause rashes in several ways.
Most drug eruptions are due to an allergic reaction to them. The reaction usually occurs when receiving a drug orally or by injection..........
