Swollen Lymph Nodes: Are They Signs Of A Serious Condition?

Consult a doctor if you suffer any of the symptoms that can occasionally go along with swollen lymph nodes, or if your lymph nodes are painfully swollen but you don’t have any other symptoms. Swollen lymph nodes that are not uncomfortable may indicate a significant issue. If a lymph node is painful or swollen and lasts more than a few days, consult a doctor as well. In some circumstances, the swollen lymph node will shrink as other symptoms subside.

How Do Lymph Nodes Function?

Lymph vessels (tubes that run through your body like veins) connect your lymph nodes to one another and carry lymph fluid. This fluid is a clear, watery liquid that travels through the nodes.

As the fluid passes through, lymphocytes work to defend you from hazardous microbes. There are two kinds of lymphocytes: B-lymphocytes (or B-cells) and T-lymphocytes (or T-cells).

Your B-cells alert the immune system when germs are present. They produce antibodies that attach to these germs.

T-cells, on the other hand, perform a variety of tasks. Some of these include the destruction of pathogens and the monitoring of immune cells, which enables your body to know when to produce more of some immune cells and less of others.

Memory T-cells are T-cells that remain latent following an infection and reawaken in response to another infection.

The lymph fluid also carry protein, waste, cellular debris (what’s left over after a cell dies), bacteria, viruses, and extra fat. The lymphatic system then filters the lymphatic fluid prior to reintroduction of the fluid into the bloodstream

What Do Swollen Lymph Nodes Mean?

Bacterial and viral illnesses are the typical cause of swollen lymph nodes. Cancer can be a cause of swollen lymph nodes as well.

Your lymph nodes, also known as lymph glands, are essential to your body’s ability to fight infections because they act as filters, capturing viruses, bacteria, and other disease-causing agents before they can spread to other parts of your body. You may notice swollen lymph nodes in your neck, chin, armpits, or groin.

If you have enlarged lymph nodes caused by an infection, treatment will depend on the reason. They may only require time and warm compresses in some circumstances.

In order to determine whether swelling is present, people can check the lymph nodes on each side of the body in parallel and compare them to see if one is larger than the other.

Many people who have swollen glands also feel discomfort when they move suddenly or tensely, such as rotating their necks forcefully, bobbing their heads, or chewing food that is tough.

Other symptoms – which depend on the underlying issue but may include a sore throat, a cough, or flu-like symptoms – frequently coexist with swollen lymph nodes.

Why Are My Armpit’s Lymph Nodes Swollen?

White blood cells, which aid in the fight against infections, are present in the watery fluid known as lymph, which also delivers waste materials away from the cells and oxygen to them.

In some parts of the body, such as the neck, armpits, and groin, swelling of the lymph nodes is more common as the body starts to work harder to remove waste. A swollen lymph node may hurt and feel sore to the touch. In some cases, it will be clearly larger beneath the skin, while in other situations, it will be smaller or deeper in the body and only feel noticeable when touched.

Lumps can appear in men and women of all ages, and the majority of them aren’t dangerous. With an armpit lump, it feels as if there is a pea or other growth under your skin in the uppermost portion of your inner arm.

In rare cases, an armpit lump can be a sign of cancer. More often, they’re due to irritation, blockages, or injuries affecting:

• Hair roots
• Lymph glands
• Muscle
• Skin

What Do Swollen Lymph Nodes Beneath the Jaw Mean? 

The most frequent causes of a lump under your chin or in your neck are bacterial or viral infections. These lumps, known as reactive lymph nodes, typically indicate that your immune system is battling one of these infections.

Common infections include colds, the flu, sinus and ear infections, tooth or gum infections, and strep throat.

Reactive lymph nodes are typically squishy to the touch, move around in your neck, and can occasionally be painful. They typically disappear when the infection has cleared up.

How to Manage Swollen Lymph Nodes?

If your swollen lymph nodes are tender or painful, you might get some relief by doing the following:

• Use a hot compress.
• Take over-the-counter pain medicine. Despite being safe for use in children older than 2 years old, aspirin should never be given to children or teenagers who are experiencing flu-like symptoms or chicken pox. If you have any questions, consult your doctor.
• Get enough sleep.
• Massage your chest to promote lymphatic drainage from your neck and chest to the lymph nodes beneath your arms by placing your hands on your collarbone and making half-circles down your chest toward your underarms. Continue descending toward your ankles, stroking your feet and ankles up and down.

How to Prevent Swollen Lymph Nodes

You wouldn’t want to prevent swollen lymph nodes as they are a sign that your body is fighting an infection or illness. To prevent swollen lymph nodes, take precautions and  avoid catching common viruses through the following:

• Cleaning hands properly.
• Do not touch your eyes or nose.
• Stay away from people who are sick.
• Clean the surfaces in your house or office.
• Get adequate rest, eat well, and work out.

When Should I See the Doctor?

Some swollen lymph nodes return to normal when the underlying condition, such as a minor infection, gets better. See your doctor if you’re concerned or if your swollen lymph nodes:

• Have emerged without obvious cause
• Are either expanding or have been there for two to four weeks.
• When you push on them, they don’t move or feel rigid or rubbery.
• Are accompanied by a long-lasting fever, nocturnal sweats, or a sudden loss of weight.

Key Takeaways

Swollen lymph nodes are typically nothing to worry about. In fact, they are a common indication that your body is effectively fending off infections. Swollen lymph nodes typically disappear within a few days. If the swelling is accompanied by significant symptoms like high fever, night sweats, or unexplained weight loss, visit your doctor as soon as possible.
