Understanding the symptoms of cold
One to three days after catching a cold virus, symptoms begin suddenly. They start with a burning feeling in the nose or throat. Next comes sneezing, a runny nose, and the feeling of being tired and unwell.
For the first few days, your nose teems with watery nasal secretions. Later, these become thicker and darker. Dark mucus does not necessarily mean that you have developed a bacterial infection.
You may get a mild cough. It won't get much worse, but it is likely to last into the second week of your illness. If you suffer from chronic bronchitis, a cold will make it worse. If you are coughing up dark material -- or if you are feeling a lot of distress low down in your lungs -- you may have a bacterial infection. These symptoms can also be caused by a cold virus other than a rhinovirus.
Usually there is no fever -- in fact, fever and more severe symptoms may indicate that you have the flu and not a cold.
Cold symptoms settle in between one and four days after you are infected by a cold virus and typically last for about three days. At that point the worst is over, but you may feel congested for a week or more. During the first three days that you have symptoms, you are contagious. This means you can pass the cold to others, so stay home and get some rest.
Except in newborns, colds themselves are not dangerous. They usually go away in four to 10 days without any special medicine. Unfortunately, colds do wear down your body's resistance, making you more susceptible to bacterial infections.
If your cold is nasty enough, seek medical attention. Your doctor likely will examine your throat and ears. He or she may take a throat culture by brushing your throat with a long cotton-tipped swab. This will show whether you have a bacterial infection, which requires treatment with antibiotics.
