Are swollen lymph nodes in the neck dangerous? What are the symptoms?

What does swollen lymph nodes in the neck mean?

The cervical lymph nodes are located in the front, sides, and back of the neck. They are important bean-shaped organs less than 1 cm in diameter that filter lymph fluid and play a vital role in the immune system by clearing out damaged cells and germs. You have hundreds of lymph nodes throughout your body. When these glands become larger than normal, healthcare professionals call it lymphadenopathy or adenopathy, or swollen lymph nodes. Swollen lymph nodes in the neck are lumps that you feel when you touch different areas of your neck. These lumps may be tender or painful when pressed. Swollen lymph nodes in the neck can occur in children and adults of any age. Neck lymph node surgery is one of the treatment options, and we will discuss the various treatment methods in more detail below.

Symptoms of Swollen Neck Lymph Nodes

The average person does not necessarily feel swollen cervical lymph nodes. However, if the lymph nodes in the neck are swollen, a doctor may detect one or more lumps under the skin when examining the neck area. The exact symptoms that may occur with swollen lymph nodes depend on the underlying cause; but common symptoms include:

• Swollen, palpable lumps in the neck
• Pain or tenderness in the area of ​​the swollen nodes
• Fever or chills
• A general feeling of being unwell or unwell
• Fatigue
• Body aches

Causes of Swollen Neck Lymph Nodes

Swollen neck lymph nodes are often a sign of an upper respiratory tract infection (such as the common cold) or an infection in nearby tissues. Viral infections are the most common cause of cervical lymphadenopathy in children. These problems are usually temporary or treatable. However, there are many possible causes, some of which are more serious. These causes fall into a few general categories:

• Infections
• Cancers
• Autoimmune diseases
• Other medical conditions
• Reactions to medications

Depending on the cause, you may also notice swollen lymph nodes in other areas of your body, such as your armpits or groin. This condition is called generalized lymphadenopathy.

1. Infections

A wide range of bacterial, viral, and other infections can cause swollen lymph nodes in the neck. Some are more serious than others. For example:

• Strep throat
• Common cold and flu
• Adenovirus infection
• Cytomegalovirus infection
• Chickenpox
• Shingles
• Rubella
• HIV
• Tuberculosis
• Epstein-Barr virus infection, such as mononucleosis or mono
• Skin infections, such as staph
• Lyme disease
• Cat scratch disease
• Toxoplasmosis

2. Cancers

Cancer can cause swollen lymph nodes in more than one area of ​​your body (generalized lymphadenopathy), and your neck may be one of these areas. Note that less serious illnesses, such as strep throat or chickenpox, can also sometimes cause swollen lymph nodes in multiple areas. For this reason, if you notice swollen lymph nodes, it is important to see a doctor for further evaluation.

Examples of cancers that can cause cervical lymphadenopathy include:

• Lymphoma
• Leukemia
• Rhabdomyosarcoma
• Thyroid cancer
• Melanoma
• Kaposi’s sarcoma

3. Autoimmune diseases

When you have an autoimmune disease, your immune system mistakes healthy cells in your body for invaders. As a result, large numbers of white blood cells are sent into action to attack and destroy this perceived threat. The accumulation of these cells in the lymph nodes leads to swelling. Examples of autoimmune diseases that can cause swollen lymph nodes in the neck (and often other areas) include:

• Rheumatoid arthritis
• Lupus
• Still’s disease

4. Other medical conditions

Other medical conditions that cause swollen lymph nodes in the neck include:

• Castleman’s disease
• Kawasaki disease
• Kikuchi-Fujimoto disease
• Sarcoidosis

5. Reaction to medications

The body’s reaction to certain medications can also lead to swollen lymph nodes in the neck. For example:

• Some high blood pressure medications (such as atenolol, captopril, and hydralazine)
• Some antibiotics (such as penicillin and trimethoprim/sulfamethoxazole)
• Some seizure management medications (such as carbamazepine and phenytoin)
• Allopurinol, which is used to treat gout or kidney stones.
• Sulindac, which is used to treat arthritis.
• Quinidine, which is used to treat irregular heart rhythms.

When to see a doctor?

Swollen lymph nodes in the neck are usually temporary and harmless and indicate that your body is fighting a minor infection, such as a cold or strep throat. Infections often go away without treatment, and the lymph node will return to its normal size once the infection is gone. But sometimes it can be a sign of a more serious problem. So be sure to see your doctor if you have any of the following:

• Severe symptoms, such as severe pain, high fever, or trouble breathing
• Swelling that lasts for more than 2 weeks
• Additional symptoms, such as night sweats and a persistent fever
• Swelling of the gland without any other symptoms (which could be a sign of cancer or an autoimmune disease)
• Feeling a hard, painless lump in the lymph node
• Rapid change in the size of the lymph node
• Swelling in more than one area of ​​the lymph node; For example, simultaneously in the neck and groin

Diagnosis

A doctor will usually diagnose swollen lymph nodes in the neck by feeling the person’s neck and asking about:

• Other symptoms
• Personal and family medical history
• Medications and possible exposure to toxins
• Lifestyle habits
• Recent travel
• Exposure to other people with infectious diseases

He or she may also order additional tests to find the cause of the swelling:

• Blood tests
• Throat cultures to check for bacterial infections, such as streptococci
• Computed tomography (CT) scan or magnetic resonance imaging (MRI)
• X-rays

If necessary, the doctor will also take a sample (biopsy) of the lymph nodes in the neck to check for cancer cells.

Treatment of swollen lymph nodes in the neck

Treatment methods for swollen lymph nodes in the neck depend directly on the underlying cause of the swelling. Healthcare professionals will choose the best treatment option based on the cause.

1. Treating swollen lymph nodes due to infections

In most cases, swollen lymph nodes in the neck are caused by the body’s fight against an infection. In such cases, the gland usually returns to its normal size after the infection is cleared. Treatment in these cases consists of two parts:

1. a) Home care (for viral infections and to reduce discomfort): Swollen lymph nodes in the neck usually do not require medical treatment; unless they are painful. The following strategies can help reduce discomfort:

• Applying warm compresses to the swollen area several times a day
• Taking over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs) (such as ibuprofen) to relieve pain
• Getting plenty of rest and drinking plenty of fluids

1. b) Medical treatment (for bacterial infections): If you have symptoms of a bacterial infection (such as strep throat), your doctor may prescribe an appropriate antibiotic to kill the pathogen
2. Treatment for Swollen Neck Lymph Nodes Due to Cancer

In more serious conditions such as cancer, your doctor will discuss treatment options with you based on the type, stage of the disease, and your overall health. Possible treatments for cancers that cause cervical lymphadenopathy include:

• Chemotherapy
• Radiation therapy
• Immunotherapy (treatment that activates the immune system)
• Surgery: This procedure, which is mainly used to manage head and neck cancers (such as throat, mouth, and tongue cancer, thyroid cancer, and melanoma), involves performing a lymphadenectomy (complete removal of the affected lymph nodes) to prevent the disease from spreading.

3. Treatment for Swollen Neck Lymph Nodes Due to HIV

In people with HIV, antiviral medications are prescribed to manage the virus. These medications reduce the amount of virus in the blood and body fluids to an undetectable level. As the virus activity decreases and the immune system strengthens, the swollen lymph nodes in the neck will resolve or significantly reduce.

4. Treatment for swelling due to autoimmune diseases

Swelling of the lymph nodes due to autoimmune diseases (such as lupus or rheumatoid arthritis) occurs when the immune system becomes overactive and attacks healthy tissues. Treatment for this type of swollen lymph nodes is directly focused on controlling the underlying autoimmune disease. With successful management of the underlying disease, the swollen lymph nodes are expected to decrease. These treatments may include the following:

• Immunosuppressive drugs: to reduce the overactivity of the immune system
• Anti-inflammatory drugs: to reduce inflammation throughout the body, including the lymph nodes

5. Treatment for swollen lymph nodes due to a reaction to medications

. In this case, the main treatment involves stopping the medication in question (under the supervision and at the discretion of a doctor) or replacing it with another medication. Swollen lymph nodes in the neck usually go away after the medication is stopped or changed.

Preventing Swollen Lymph Nodes in the Neck

Swollen lymph nodes in the neck are not always preventable and often occur suddenly, such as when a person has a viral or bacterial infection. In other cases, the swelling is caused by illnesses that affect the whole body. However, you can prevent many of the infectious diseases that are the main causes of swollen lymph nodes in the neck by following a few simple tips:

• Hand washing: Be sure to wash your hands when necessary, such as after touching shared objects or caring for a sick person.
• Disinfecting surfaces: Disinfect surfaces such as workbenches, counters, and doorknobs in your home and workplace.
• Boosting your immune system: Boost your immune system by eating nutritious foods and getting enough sleep.
• Get vaccines: Get the vaccines your doctor recommends (such as the flu shot).

Since the lymph nodes in the neck are directly related to the health of the head and face, it is also important to prevent infections in that area:

• Oral hygiene: Brush and floss regularly. Tooth and gum infections are a common cause of swollen lymph nodes under the jaw and neck.
• Avoid contact with sick people: Avoid close contact (such as kissing or sharing utensils) with people who have infections such as mononucleosis or a severe cold as much as possible.
• Protect your scalp and face: Take care of cuts and scrapes on the head and neck, which can be a way for bacteria to enter.

Conclusion

Swollen lymph nodes in the neck are a common condition and are usually not dangerous. In most cases, this swelling is a temporary reaction of the body to an infection. Tenderness and mobility of lymph nodes usually indicate benign and transient lymphoid reactions.
