For painful sinuses and the accompanying headache - beat 2 egg whites (stops them being slimy and difficult to handle). Spread out on a gauze (or cloth) and put over your face (avoiding eyes). Put another cloth over (optional). Lay down on your back and go to sleep. The heat/temperature will harden the gauze. Suggest you leave it on as long as you can. You will be pain free and as a bonus will get a facelift.
I have used this remedy for migraines and hard to shift headaches and have always gained relief.
