I get sinus infections all the time. Sudafed, Neti pots, Vicks Vapo-Rub, almost anything that helps open up your sinus passages, all help but don't really solve the problem.
When they get their worst I go to the doctor and he loads me up on anti-biotics but I don't like to do that too often.
Hope you feel better soon.
