Nasal Irrigation with saline is effective. You might want to add a course of Olive Leaf Extract. The label direction will tell you that the reccommended dosage is one capsule. It is a good idea to gradually increase your doseage to test for any allergic sensitivities but if you discover that you have no reactions very large initial doses work best (5000mg-3 times a day). It is primarily an antiviral herb but in large doses works well with other tyypes of infection. I have sucessfully treated my own tooth abcess with it but remember that I was my own "patient". I do suggest that you research Olive Leaf Extract. On a more "medical" path which I am not really suggesting but giving you some added information, Bacitracin ointment on a cuptip gently rubbed in the nasal cavity is an effective means of reducing sinus swelling. Sometimes the problem is low grade chronic staph infection. I am not a doctor and only speaking from my own experiences. I do prefer not using any types of anti-biotic treatments that aren't "whole herb" based however. Olive Leaf Extract is the best I have found.
