In brief: 36 to 48 hours

Typically a pt who has a hist of HAE attacks can "sense" hours or even a day or two before.
The swelling is noted over a 6-24 hour period and typically peaks at 36-48 hours. The most important point here is to treat at the very first symptom with your on demand medication. It's important to recognize even the slightest sense of a laryngeal attack gets med ASAPand then to the ER to be watched.

In brief: Hereditary angioedem

Very difficult to say since hae patients can have many attacks, even oneon top of another. The "typical" time course for an angioedema attack is a 72-hour progression to fully swollen and then another 72-hours until resolution (with or without therapy, which will shorten time course).
