What are the dangers of giant urticaria?

The harm of giant urticaria is mainly due to its sudden occurrence, and the patient may not be able to prevent it. In particular, this urticaria suddenly appears, causing obvious tissue edema. If this edema occurs in the throat, it may suddenly show symptoms of suffocation, so this harm is relatively large. If giant urticaria occurs on other skin surfaces, such as the lips or external genitals, the general harm is not great. The cause of giant urticaria is not very clear, sometimes it may be caused by allergic factors, and this skin damage may resolve itself after a few hours. If this skin damage is accompanied by systemic symptoms, prompt treatment is required.
