Lymph nodes are located in many parts of the body, including the neck, armpit, chest, abdomen (belly), and groin. They contain immune cells that can help fight infection by attacking and destroying germs that are carried in through the lymph fluid. There are hundreds of lymph nodes throughout the body.
Lymph nodes filter substances that travel through the lymphatic fluid, and they contain lymphocytes (white blood cells) that help the body fight infection and disease. There are hundreds of lymph nodes found throughout the body. They are connected to one another by lymph vessels.
Lymph (from Latin, lympha meaning “water”) is the fluid that flows through the lymphatic system, a system composed of lymph vessels (channels) and intervening lymph nodes whose function, like the venous system, is to return fluid from the tissues to the central circulation.
The Causes of Swollen Lymph Nodes For the most part, your lymph nodes tend to swell as a standard response to infection. They may also swell due to stress. Some of the most common illnesses associated with swollen lymph nodes include colds, ear infections, the flu, tonsillitis, skin infections, or glandular fever.
Swollen lymph nodes usually occur as a result of infection from bacteria or viruses. Rarely, swollen lymph nodes are caused by cancer. Your lymph nodes, also called lymph glands, play a vital role in your body’s ability to fight off infections.
Lymph is formed when the interstitial fluid is collected through tiny lymph capillaries (see diagram), which are located throughout the body. It is then transported through lymph vessels to lymph nodes, which clean and filter it.
Simply speaking, the difference between blood and lymph is that lymph, unlike blood, is colourless and it is a return fluid from tissues to the central circulation. Furthermore, interstitial fluid is present between the cells in the various tissues and it enters the lymph capillaries.
- The removal of excess fluids from body tissues. …
- Absorption of fatty acids and subsequent transport of fat, chyle, to the circulatory system.
- Production of immune cells (such as lymphocytes, monocytes, and antibody producing cells called plasma cells).
Dehydration is believed to cause mild swelling of the lymph nodes, so that may be responsible for some of the swelling you feel.
Swollen glands should go down within 2 weeks. You can help to ease the symptoms by: resting. drinking plenty of fluids (to avoid dehydration)
Swollen lymph nodes will feel like soft, round bumps, and they may be the size of a pea or a grape. They might be tender to the touch, which indicates inflammation. In some cases, the lymph nodes will also look larger than usual. Lymph nodes appear in parallel on both sides of the body.
Antibiotics are not used for a swollen lymph node that is not infected. You can use warm compresses and pain medicine to treat this condition. The pain will get better over the next 7 to 10 days. The swelling may take 1 to 2 weeks or more to go away.
- Apply a warm compress. Apply a warm, wet compress, such as a washcloth dipped in hot water and wrung out, to the affected area.
- Take an over-the-counter pain reliever. …
- Get adequate rest.
Lymph node removal is a surgical procedure to take out one or more of your lymph nodes. Your doctor may recommend you have this procedure if you’ve been diagnosed with cancer. There are two main reasons for removing lymph nodes. If you have cancer, one or more lymph nodes may be removed to check whether it has spread.
- Drink plenty of water.
- Eat a healthy diet rich in alkaline foods and vegetables that provide a full range of vitamins, minerals and nutrients.
- Include healthy fats in your diet.
- Exercise daily, including both aerobic and anaerobic physical activity.

Lymph is a clear-to-white fluid made of: White blood cells, especially lymphocytes, the cells that attack bacteria in the blood.
Lymphatic circulation The portion of blood plasma that escapes is called interstitial or extracellular fluid, and it contains oxygen, glucose, amino acids, and other nutrients needed by tissue cells.

Lymph nodes: Lymph nodes are bean-shaped glands that monitor and cleanse the lymph as it filters through them. The nodes filter out the damaged cells and cancer cells.
The U.S. National Academies of Sciences, Engineering, and Medicine determined that an adequate daily fluid intake is: About 15.5 cups (3.7 liters) of fluids a day for men. About 11.5 cups (2.7 liters) of fluids a day for women.

No, swollen lymph nodes aren’t fatal. Alone, they’re simply a sign that your immune system is fighting an infection or illness. However, in rare cases, swollen lymph nodes can point to serious conditions, such as cancer of the lymphatic system (lymphoma), which could potentially be fatal.
It’s time to call your doctor if: Your lymph nodes swell for no obvious reason. They increase in size and you have had them for more than two weeks. The node feels hard and doesn’t move when you push on it.
In fact, lymph nodes are not actually glands. They are small bundles of white blood cells that are present in multiple areas throughout our body. One of the ways the body’s immune system responds to infections and inflammation is to greatly increase the number of white cells in the lymph nodes causing them to swell.
Neck pain along the lymph nodes can be caused by enlargement of the lymph nodes (lymphadenopathy) or inflammation of the lymph nodes (lymphadenitis). Traditionally, infectious etiologies are the main cause of lymphadenitis.
- Nodes that increase in size.
- Nodes that are painful to touch.
- Nodes that are soft or matted together.
- Redness or red streaking of the skin over nodes.
- Nodes that are filled with pus (an abscess)
- Fluid that drains from the nodes to the skin.
Infections are one cause of enlarged lymph nodes. Shortness of breath can accompany respiratory conditions, including infections. If you are having difficulty breathing, seek immediate medical attention. Talk to your doctor anytime you are concerned about your symptoms.
