A sore or itchy throat and cough are two of the most common symptoms that bring people to a doctor. These symptoms often occur together, as irritation that causes your throat to be sore can also trigger a cough.

Sore throats occur in people of all ages and prompt at least 10 million healthcare visits each year, according to the Centers for Disease Control and Prevention. Most sore throats occur due to a viral infection, which typically clears without medical treatment in roughly 5 to 7 days.

Sinus congestion, or a stuffy nose, often accompanies sinusitis, but the former can occur for other reasons, such as a cold. Chronic sinusitis is more prevalent than heart disease or asthma and affects 37 million Americans every year, according to Mountain States Health Alliance.

With steadily rising levels of environmental pollutants permeating the air, it is no surprise that, according to the Center for Disease Control, sinusitis currently affects 30.6 million American citizens—and that number is growing daily.

One task your nose is responsible for is the moistening and warming of air before it enters your lungs. The inside of your nose contains tiny blood vessels that lie very close to the surface of your nasal passages. Nose bleeds, also referred to as epistaxis, occur when these tiny blood vessels get damaged.

Sinus pressure and nausea are common symptoms of a wide variety of illnesses and often occur together. Sinuses are moist air spaces in the skull, behind the face. The spaces may fill with fluid, causing pressure behind the eyes, cheekbones and nose.
