It is more likely that you will get urticaria or angioedema if your parents had/have it too. This is also true if your parents have allergies like allergic rhinitis, skin allergies, chest allergies or even food allergies. These cases are called hereditary, which means that they run in families. Your parents can pass it to you and/or you can pass it on to your children.
Urticaria alone or with angioedema is more common in women, whereas, angioedema alone is more common in men. A lot of times, urticarial attacks occur without anyone understanding why they happened, the first time. It is likely that it will need to happen again to create an understanding of the cause of the attacks.
