Sinus headaches are usually characterized by a throbbing pain in your forehead or behind your eyes that may increase when you lean forward or lie down. You may also experience pressure between your eyes or tenderness in your cheekbones, a sore throat, runny nose or cough. These symptoms may be a result of your nasal passages becoming swollen due to environmental irritants, allergies, or even a cold. As cold and flu symptoms can be very similar, please refer to the following differences: A cold is characterized by a runny nose, watery eyes, stuffy nose, and congestion, sneezing and coughing. These symptoms build over 48 hours and may last for 3-10 days. Unlike the cold, flu symptoms such as fever and chills appear very quickly and may last for 7-14 days (and may linger for up to 3 weeks). Other symptoms include body aches and pains, weakness and fatigue.
