Swollen Lips

Sometimes my lips swell up to several times their normal size. They tingle and burn beforehand and the swelling lasts for a few hours. What’s causing this?

The most likely explanation for this would be an allergy to something you are eating but identifying what can be difficult. Common culprits include nuts, wheat, cow’s milk, hen’s eggs, shellfish, citrus fruits and strawberries. Try keeping a food and symptom diary for a few weeks and you may notice a pattern. Food allergies can sometimes cause the tongue to swell and make you wheezy so make sure you keep antihistamine tablets at hand in case this should get worse.
