9.Headache
Many things can cause this, but a cold isn’t usually one of them. It’s a common flu symptom and can be a sign of a sinus infection. But painful sinuses, the spaces above and around your nose, can also be caused by hay fever, or rhinitis.
10.Chest Tightness or Pain
This is a telltale symptom of a more serious respiratory infection, like bronchitis. That can also make your chest feel tight, and you may have a hard time taking a deep breath. Sharp chest pain that feels worse when you cough can be a sign of pneumonia, and chest tightness is also a common symptom of asthma. Get medical help right away for any chest pain or pressure. It can also be the sign of life threatening conditions such as a heart attack or a blood clot in the lung.
