Angioedema: Lip swelling is a common area for angioedema to occur. Other areas are tongue, around eyes and genital area. Sometimes it can be top, bottom, left or right side of lip. The reaction is generally similar to a hive but at a deeper tissue level. Triggers can be allergy to medication, foods, or idiopathic (unknown). An unusual hereditary angioedema can affect the lips and throat.
