Reproductive system introduction Video transcript The heart pumps blood throughout the body, and it pumps so powerfully that it actually squeezes some fluid out of the capillaries. And that fluid becomes lymph.
Evaluation Not every person with swollen lymph nodes requires immediate evaluation by a doctor. Warning signs In people with swollen lymph nodes, certain symptoms and characteristics are cause for concern. They include A node that is an inch or more in diameter A node that is draining pus A node that feels hard Risk factors for HIV infection such as being stuck with a needle used by another person or high-risk sexual activities or tuberculosis such as living or working with a person who has tuberculosis or having recently moved from an area where tuberculosis is prevalent Fever or unexplained weight loss When to see a doctor If a lymph node is very painful or draining pus or other material, people should see a doctor right away.
Other people should call their doctor.
The doctor will decide how quickly they need to be seen based on the presence of warning signs and other symptoms.
For people who have no warning signs and otherwise feel well, a delay of a week or so is not harmful. Doctors then do a physical examination.
What they find during the history and physical examination often suggests a cause of the swollen lymph nodes and the tests that may need to be done see Table: Doctors ask Where the swollen nodes are located How long nodes have been swollen Whether the person has pain Whether the person has recently had an injury particularly cat scratches and rat bites Whether the person has an infection or symptoms of an infection for example, a runny nose, cough, fever, sore throat, unexplained weight loss, or tooth or gum pain Doctors then do a physical examination.
Doctors check for fever and examine areas where lymph nodes are found. Doctors check the person for any signs of infection or lumps elsewhere in the body.
People who have swollen lymph nodes throughout the body usually have a disorder that affects the entire body. However, people who have swollen lymph nodes in only one area may have a disorder that affects only that area for example, an infection or more widespread disease. Sometimes, the history and physical examination findings suggest the cause, as for example when the person has an upper respiratory infection or a dental infection see Table: In other cases, findings do not point to a single cause.
People with warning signs are more likely to have a serious disorder, but people with lymph node swelling and no other symptoms may also have a serious disorder.
Nodes that are hard, very enlarged, and do not move when pushed may indicate cancer. Tenderness, redness, and warmth in a single enlarged lymph node may indicate an infection of the node.Study 89 ch.
