Hello. Welcome to hcm.
It is a case of anaphylaxis
,probably to cheese.
I advice you to visit ER immedietly so that you can get a shot of antihistaminic. You should be put on antihistaminics,ondansetron
. Avoid taking anything by mouth and hospital stay with i.v. Fluids is a must.
Later on recovery,try to find out the allergen causing these symptoms.
All the best
