Will Taking Levaquin Help Cure Sinus Infection?

I had a cold that turned into a sinus infection. I saw the doctor and she gave me levaquin and cough syrup with codeine but the cough syrup keeps me up at night so I only take it in the evening to settle the cough. It s started to get better get a little better but I m still having headaches, green discharge and a cough. I received my flu shot and a pneumonia vaccination two days ago and have had sweats the past two nights. Could the sweats be caused by the shots or are they part of the virus and should I go back to the doctor?
