∙ 13y agoThe lymphnodes swell because they are essentially where all of the dead bacteria and white cells go when the infection is being fought. That is why doctors feel them when you feel sick, for example, strep throat. There are two right below each of your ears, some near your armpits, and others.

∙ 11y agoBecause the lymph nodes contain white blood cells and when they sense bacteria or a virus the release these cells to fight off the infection/virus, thus causing the nodes to swell. If the nodes are tender and easy to move there is nothing to worry about this just means they are fighting of a virus. When they are hard and don't hurt that is when you need to go to the Doctor

∙ 13y agoWhen they swell, it's a sign that they're fighting off the infection. Lymph nodes begin to produce plasma cells (type of white blood cell) once a B lymphocyte correctly identifies a foreign antigen. These plasma cells display the same antibodies as the successful B lymphocyte and secrete the antibodies to disable the antigenic particles or organisms. This process is called humoral immunity.

Can lymph swell when you have sore throat from cold?
More white blood cells are being produced. Because they multiply to kill large areas of the disease-causing pathogens. And your glands begin to swell painfully. ouch! /\ Close but no cigar. In order to understand why lymph nodes swell you have to understand what lymph nodes do. Lymph nodes act as a filter system for Lymph Fluid, or all of the excess fluid our body produces. Lymph fluid is responsible for carrying nutrients all over the body and delivering said nutrients through the blood stream. Lymph nodes filter out infections as they are carried by the Lymph fluid from one part of the body to the other. Lymph nodes are found in several places on the body, so as an infection tries to spread, using the Lymph fluid as it's guide, the Nodes trap the infection in an attempt to eradicate it. Once the infection has been trapped your white blood cells begin to attack it aiding in the recovery process. The bi product of all of the activity and excess infection in the nodes, is swelling or pain. The nodes themselves do not multiply, they are located in several areas throughout your body, the neck, the armpit, and the groin are the most commonly noted sore areas during a sickness. If you notice tenderness in any of these areas please contact your physician as it may be a sign of infection, or something more serious.
