The lymphatic system is made of channels throughout your body that are similar to blood vessels.
Lymph nodes are small glands that filter lymph, the clear fluid that circulates through the lymphatic system.
Lymphadenopathy is another name for swelling in the lymph nodes.
Swollen lymph nodes are one sign that your lymphatic system is working to rid your body of infection and illness.
Lymph nodes swell when an infection occurs in the area where they’re located.
For example, the lymph nodes in the neck can become swollen in response to an upper respiratory infection, such as the common cold.
Serious conditions, such as immune system disorders or cancers, can cause lymph nodes throughout the body to swell.
Swollen lymph nodes can be as small as peas or as large as cherries.
They can be painful to the touch, or they can hurt when you make certain movements.
If you’ve recently become ill or had an injury, let a doctor know.
This information is vital in helping them determine the cause of your symptoms.
Swollen lymph nodes may become smaller on their own without any treatment. In some cases, the doctor may wish to monitor them without treatment.
