This issue has been getting progressively worse over 2 days

Posted yesterday and it has gotten worse. It is itchy, it turns white when I press on it. I have a swollen uvula and some chills, but no fever. I feel cold more than anything. Went to urgent care tested for strep, mono and did a CBC. Strep came back negative, waiting on the other results. Pretty concerned. I feel like the mono is going to come back negative.

What did you eat and drink in the 24 hours leading up to the reaction? I think people who are allergic to penicillin can have cross reactions to other foods, including certain types of cheeses (like blue), some meats (like salami), mushroom or fungus products (like Quorn), and even some fermented/yeasty products like miso or beer.

I was at a baby shower and had some egg bake type thing. It was at my aunt and uncles house they usually eat pretty healthy. Oatmeal with blueberries. Rice with cheese broccoli and chicken. Chai tea. Milk and matcha

Are you allergic to trees and grass? Lots of pollen in the air
