allergies or infection?

This is a terrible time for allergies. A sinus infection does not get better, even with OTC medications. If it's been more than a week and nothing is helping with the pain and you have some serious gross looking discharge, I'd cast my vote for seeing a doctor. I have had some really bad infections without running a fever. If it's not a sinus infection and you haven't seen a doctor for allergies, maybe now would be a good time to go see one. OTC allergy meds sometimes help. Saline nasal spray really helps if you make the effort to use it at least 3 times a day.
