Angioedema: Triggered by stress.
J Pak Assoc Derma Jan ;30(3):516-8.

Angioedema is a deep   swelling of subcutaneous tissue or mucosa because of increased vascular permeability. It is commonly seen as manifestation of an allergic reaction. It may occur with or without urticaria, or may be recurrent secondary to triggers like trauma, drugs, autoimmune diseases, physical or emotional stress. Severe angioedema can compromise airway patency. Avoidance of known triggering   stimuli is the primary strategy in any treatment.
