10 Causes of Urticaria
Cause #1: Allergies to Food
The most common cause of hives is an allergy. People can develop allergies to many different things and one of the most common things is food. Common foods that cause allergies are citrus fruits, milk, nuts, and shellfish.
If you experience hives in addition to symptoms like a runny nose, sneezing or coughing, watery eyes, or other respiratory problems, it might be safe to assume that you have an allergy. If this is the case, try to identify the allergen and avoid exposure to it.
