My opinion is that zpak is horrible for sinus infections. My doctor even told me so. He won't even prescribe them unless it's for something very minor. Sinusitis is not minor and can lead to bad things if not taken care of. I would suggest asking your doc to prescribe you something else like levaquin which a very broad spectrum antibiotic (i.e. Kills a lot of different bacterial agents). It can take longer to get rid of a sinus infection than something like bronchitis because of where the bacteria are.

Thanks
Will look in to Levaquin,

Do you have any reccommendations for dealing with the pain?

Thanks again,

Bill
