Most cases of hives are caused by ingestion of a substance. Medications, allergens and many foods or food additives can cause hives suddenly, even in small amounts. Foods such as fish, shellfish, nuts, eggs, chocolate and cheese are the usual causes. Do you have allergy to any substances? Inhaled Allergens such as pollen, mold spores, animal dander and house dust also contribute to the flare ups of hives. Did this condition appear suddenly? What are other signs or symptoms present? Avoidance of the offending agent may help. Try not to scratch the affected area and wear loose clothing that do not put pressure on the skin. If the substance or allergy responsible for your urticaria can not be found, the symptoms of urticaria will need to be treated. Antihistamines are the primary medications used to control hives and stop the itching. If this persists, it would be best to see your doctor for further evaluation and management. Take care and keep us posted.
