How common is skin swelling in angioedema?

Angioedema causes localised puffiness that may affect the lips, eyelids, face, hands, feet, or genital area. The skin can feel tight, warm, or uncomfortable; unlike hives, the swelling may sit deeper and may not have a raised itchy welt over it. Episodes can follow a medicine, food, infection, insect exposure, or another trigger, though the cause is not always clear.

Swelling can have many explanations, so the symptom alone does not identify [Angioedema](/conditions/angioedema/). The timing, affected areas, associated rash, and medicines taken are important clues.

Stop and record any new medicine, food, or exposure that preceded the episode, but do not stop a prescribed medicine without medical advice unless emergency professionals tell you to. Avoid rubbing the swollen area and follow an existing allergy action plan. Arrange prompt clinical advice after a new or unexplained episode, especially if swelling returns. More information about [Skin Swelling](/symptoms/skin-swelling/) can help you describe the changes.

Call emergency services immediately for swelling of the tongue or throat, trouble breathing or swallowing, voice change, dizziness, faintness, or rapidly worsening symptoms. Do not wait to see whether the swelling settles. Emergency treatment may be needed even when skin changes seem limited.

Could a medicine or exposure have triggered this episode? What should I do if the lips or tongue swell again? Do I need an emergency action plan or further allergy assessment?
