41yr female have had sinus headaches for years.constant sinus pressure in cheeks - nose - teeth. This is a mild thing everyday. But every other week pressure moves into forehead and cause left side headache for 3 days so bad cant move. If I take a 12 hr Sudafed on the mild days - pressure is taken away until next day. On headache days nothing works -
