11.Shortness of Breath
Colds can cause a very stuffy nose, which make breathing a little harder, but real shortness of breath is a sign of something more serious. It’s a common symptom of asthma or a flare-up of COPD, and it also can be from a serious infection, like bronchitis or pneumonia.
12.Ear, Face, or Eye Pressure
If you feel pressure in your ears, it may mean you have a sinus infection. That also causes pain and pressure around your eyes, cheeks, or forehead that gets worse when you bend over. And if you feel fullness in one ear, it may be a symptom of an ear infection.
