Urticaria (Hives) Types, Symptoms and Causes

Most of the persons have a strong desire to scratch their skin as the swelling is rather itchy, but it is important to resist this desire. The most commonly covered ‘territories’ are the human face and limbs (both hands and legs). You can notice a red flare around the rash in some cases. The welts will go away in twenty-four hours, so the patients should not worry too much. However, if you do nothing, the new welts may show up. Still, they will occupy just a particular zone.
