Runny noses are a common symptom of the common cold and usually last about 7 to 10 days. While the runny nose may start to improve after the first few days of having a cold, it may take up to two weeks for the symptoms to completely go away.
Causes of Runny Nose
A runny nose is caused by inflammation and swelling of the nasal passages. This swelling can be caused by a variety of things, including exposure to allergens, cold temperatures, air pollution, and even certain medications. The most common cause of a runny nose is the common cold, which is caused by a virus.
Treating a Runny Nose
When a person has a cold, the best way to treat a runny nose is to use over-the-counter medications such as decongestants or antihistamines. These medications can help reduce the swelling in the nasal passages and provide temporary relief from the symptoms. In addition, drinking plenty of fluids and getting plenty of rest can also help to soothe the symptoms of a cold. In some cases, a person with a cold may need to see a doctor for antibiotics if the cold has become more severe.
