Best thing we have done for Sinus issues. Started taking Generic Bee Pollen from Walmart. Take one per day and my wife and I have not had that much of an issue with sinus issues.
Now its going to take around 3 months to build up and work in your body. Its not an overnight deal. We were both going to the doctor all the time for shots and stuff. After starting the Bee Pollen in Jan 15 years ago, we now might take one box of Sinus meds per year. Where we were taking a couple of boxes per month. Again it works, but takes from 2 to 3 months of taking it to build up and start working.
