Maybe go the your pharmacy, and see if they don't offer any low-grade antibiotics over the counter. Something like Erythromyacin isn't too strong and it should be effective. Try some sore throat syrup medication like Robitussin for cough and cold, or Tylenol for flu, which has Tylenol in the syrup for pain. If the pain gets really bad you can get 222s at the pharmacy in Canada, but they can be addictive too. If this thing gets worse you are going to have to see a doctor. There is socialized medicine there. Is there a college near you that might have a student health center? That might be a place to try.
