Hives and swelling are considered to be different expressions of the same problem. Hives occur mostly on the arms, legs and torso, while swelling occurs around the lips, eyes, hands feet and genitals and can involve the tongue and throat. It is simply that the skin and mucous membranes in different areas swell in different ways. How long the problem has been ongoing is also important.
Sometimes, hives last for six weeks or more, a condition called chronic (or idiopathic) urticaria. Often, no cause is found for this chronic condition, and it usually goes away on its own after several weeks. Symptoms. Hives appear as wheals (swellings) on the skin, sometimes pink or red and surrounded by a red blotch. Typically round or oval, hives often itch. Hives vary in size, and some may blend to form larger areas of swelling. Hives can affect skin on any area of the body, especially the trunk, thighs, upper arms and face.
