Cure for urticaria and when do u treat it?

Find the cause. Hives lasting less than six weeks are often triggered by an external factor entering your body like a food or a medication. History & sometimes allergy testing can help you find the culprit. Your doctor or an allergist can help. If hives make you uncomfortable they should be treated.Hives should also be treated when accompanied by swelling of the lips or to tongue. Anaphylaxis is another story.
