I have tried over-the-counter medications for sinus congestion yet nothing seems to work. any ideas?

Sinus congestion: Try irrigating your nose with saline or hypertonic saline. Regular saline is a mixture or one teaspoon kosher salt to one quart of water, tap or boiled. It does not matter. For hypertonic and more congestion add 3 tsp salt to one quart of water. 50 cc each nostril 4 times a day. You can add some baking soda, a pitch, for better ph balance. Good luck.
