Urticaria Treatment In Delhi

Some people experience urticaria one to two times in their lifetime, but some may suffer from chronic or frequent hives.

Hives are formed due to the excess release of histamines into the skin by the overactive immune system. This leads to the formation of red, pink, raised, and itchy wheals (swelling) to appear on the skin. The hives look exactly similar to an allergic reaction. They can last from a few minutes to hours and fade away after 24 hours, leaving no trace.

Sometimes angioedema can occur in mucosa like  eyes, nasal, throat, genitals, lips which causes excessive swelling and discomfort.

What causes itching skin conditions in hives?
The mast cells present underneath the lining of the skin, lungs, and eyes are designed to kill parasites and worms, and they contain bags filled with chemicals, including histamine. When the histamines are released into the skin, they cause redness, itching, swelling, and cause hives. The condition of hives can affect any part of the body but is common to the neck, arms, and legs. The condition generally rises in clusters, with one cluster getting worse as another gets better. The rashes or wheals of hives are itchy, and their size may range from a few millimeters in diameter or several centimeters. They may appear round-shaped or shaped like rings or maps.
