Call the health center, you usually get an appointment within a week or so. And if you have some kind of paper that says you're unemployed, you don't even have to pay anything. Tell the doctor what's been going on and you should get either a referral to the allergy clinic or a referral to testing.

I really find it a bit worrying that your allergies are 'advancing'. It could be peanuts next as they're a very potent allergic agent.
