Swelling above my upper lip—what could it be?

Hey there,
I woke up this morning with some swelling on my face—well, more like near my nose, if that makes sense. It doesn’t actually hurt right now, but yesterday I had this really nasty canker sore right above my gum line that was killing me. I’m wondering if maybe it’s the dairy? I've been drinking a bit more cow's milk lately, and I had that sore for about two days before I finished a large glass of milk last night—and then suddenly, everything started swelling up. On top of that, I tried putting some honey on the sore yesterday to soothe the inflammation—kind of a desperate move, honestly—so I'm thinking maybe the honey caused an issue too? Who knows.

I’m planning on heading to the doctor, but I figured I'd try to gather some info here first.

Has anyone dealt with food allergies before? Like, has anyone experienced facial swelling from something they ate, or maybe have some insight into how allergy testing works?

It could be an allergy, or maybe you’ve just got a canker sore flared up. Those things tend to swell, too—especially if it’s on the inside of your lip. I’ve had them feel like a little hard lump before.

Do you get these sores often? Honestly, for canker sores, making a strong sage tea and using it as a mouthwash 2 or 3 times a day works wonders. Just swish and spit. It’s a proven fix; they clear up fast. 👍

Avoid those foods you think are triggering the allergy (like milk or honey) until you actually sit down with a doctor and see what they have to say.

I don't think we're looking at an allergy here—it would be quite a coincidence for an allergy to manifest precisely where the canker sore is located.
It's more likely just a localized inflammation—perhaps triggered by applying various substances to the area.
