Sinus Medication Solution

This statred as a cold a little over a week ago, with slight vision problem, similar to what I have when I get a sinus headache. I called the doctor on Thursday because i was stilled stuffed up and my vision was a little worse. I started a course of antibiotcs and decongestants, it has been 3 days. So far my vision has not improved. Has anyone had something like this? Is this more than just a side effect of my sinus infection?
