It doesn't need to be a new substance for the allergy to be new, sadly. You might just suddenly be allergic to something that's always been around, like pet hair or dust mites. :(
Easiest way to test this would be getting antihistamines from the closest pharmacy (prescription-free, dirt cheap, and usually without much in the way of side-effects other than sleepiness), popping one and seeing whether your ability to breathe normally returns within the hour. If it works, you can avoid a trip to your GP (who absolutely will prescribe you antibiotics you don't need) and go to a specialist right away.
But then, you also might have a virus or bacterial infection after all. *shrugs* Either way, I'm crossing my fingers for you that it goes away ASAP! :)
