Swollen eye?!

Hi random but google can’t help me and it’s night so can’t consult a doctor but my right eye has swelled up so much it’s almost closed. It happened over literally 10 minutes. There’s no itching and it’s not teary. It’s just got so fat I used no new product but I ate something I’ve never eaten before. Would that cause an eye to swell? I’m so confused it won’t go down 😂. I have a chest infection and it’s making me paranoid I can’t breathe like an allergic reaction so pls ease me from my dramatic thoughts

Edit my right side of my face is swelling errr ??
