One side of my lip is swollen and so painful :(

[Mummysharkdoodoodoo]

I think it’s a blister? It’s so swollen on the left side it looks like Iv had a dodgy lip injection. It feels hard and it’s so painful. There’s the white blister bit inside that I keep biting 😒😒

It’s so painful! What do I do? I’m more worried about the swelling, never had it before with an blister/ulcer

Cold sore?

I think so, or google said a canker sore? Iv had one before but never this painful or swollen!

I’ve had these, you need either antibiotic cream or antibiotics. You can ice it to make it less swollen and sore but the hard lump inside stays til you get antibiotics.
They’re horrible, I feel for you OP

Could it be a food allergy - I've had it before with nuts or tomatoes.
