Lips tingle after eating nuts
You bite into a walnut, a cashew, or a peanut. Within minutes, your lips tingle, itch, or feel a little puffy. The odd feeling may spread to your tongue or the roof of your mouth.
This is often a sign that your body reads a protein in the nut as a threat. Some people react to the nut itself. Others react to pollen that looks a lot like the nut protein, so raw nuts may tingle while roasted ones do not.
A tingle can stay mild for years. It can also be the first step of a bigger reaction on some other day. So this sign is worth taking seriously, even when it fades in a few minutes.
When to see someone
Call for emergency help if your throat tightens, your voice goes hoarse, you wheeze, or you feel faint. See a doctor soon if your lips swell, you break out in hives, or you throw up. Ask about allergy tests and whether you need an adrenaline pen.
Below are home and folk remedies linked to food allergy. Each one has a grade that shows how strong the evidence is, not a promise of results. Talk with your doctor before you try any of them, and never use one in place of emergency care.
