Hi, I was just eating pizza w friends...nothing unusual. From a shop we frequent, no new ingredients. I didn t burn my mouth, but I could feel my lips swelling. Only on my left side. The left side of my chin feels weird, and my left cheek feels funny, and the lips are swollen, but since I took one antihistamine pill, the swelling see,s to have stopped, but hasn t really gone down. No numbness on my left side other than my face...no dizziness or slurred speech. Does this sound like an allergic reaction to something?
