Hives frequently occur following an infection or as a result of an allergic reaction such as to medication, insect bites, or food. Psychological stress, cold temperature, or vibration may also be a trigger. In half of cases the cause remains unknown. Risk factors include having conditions such as hay fever or asthma.
Hives is an outbreak of raised, itchy, sometimes reddened patches of skin and bumps that are frequently caused by allergic reactions to food, drugs, chemicals, cold, sunlight, etc. Foods that can cause allergic hives are shellfish, nuts, peanuts, eggs, wheat, and soy. Hives can occur anywhere on the body but are usually seen on the extremities (arms and legs). Hives can also be caused by the friction from hot, restrictive clothing such as bra straps or tight elastic bands in panties. Hives are not contagious and can not be passed from one person to another by contact.
