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.
Often times hives are an allergic reaction to foods, insect stings, sun exposure, drugs, or plants that can cause an allergic reaction. Other possible causes can be stress or infections. There is also type of hive called angioedema. Angioedema is swelling that happens beneath the skin.
