Swollen Occipital Lymph Nodes: Causes and Treatment

What is the Occipital Lymph Node?

The occipital lymph nodes are located in the occipital region of the head, which is at the back of the head near the neck. These lymph nodes drain lymph fluid from the scalp and neck area.

The Lymphatic System

The lymphatic system is part of the immune system and functions to filter lymph fluid and remove toxins, waste, and pathogens. Lymph fluid flows through lymphatic vessels and passes through lymph nodes located throughout the body. Lymph nodes filter the fluid and contain lymphocytes that can activate immune responses.

Causes of Swollen Occipital Lymph Nodes

There are multiple possible causes of swollen or enlarged occipital lymph nodes. This can result from localized infections, underlying medical conditions, or cancers that activate the immune response in the lymph nodes and cause inflammation and swelling.

Infections Causing Swollen Occipital Lymph Nodes

Viral Infections

Viral infections in the head and neck area often lead to swollen occipital lymph nodes. The immune system responds to the virus and activates lymphocytes in the lymph nodes, resulting in inflammation and enlargement.

Common viral infections that may cause swollen occipital lymph nodes include:

• Common cold
• Flu
• Mononucleosis (mono)
• Mumps
• Rubella
• Measles

Bacterial Infections

Bacterial infections can also trigger enlarged occipital lymph nodes. Bacteria that commonly affect the scalp or cause respiratory infections, including sinus infections, may impact the occipital nodes.

Types of bacterial infections known to cause swollen occipital lymph nodes include:

• Staphylococcus or streptococcus infections of the scalp
• Tuberculosis
• Typhoid fever
• Bacterial meningitis
• Syphilis

Other Causes of Swollen Occipital Lymph Nodes

Many other conditions, including underlying health issues or cancers, can sometimes contribute to or cause occipital lymph node swelling, such as:

• HIV/AIDS
• Autoimmune disorders
• Skin irritation, cuts, abrasions or piercings
• Skin cancer or lymphoma
• Immunodeficiency

Swollen Occipital Lymph Nodes and Rheumatoid Arthritis

Rheumatoid arthritis is an autoimmune disease that mainly attacks the joints but can also affect other tissues and organs like the skin and eyes. Rheumatoid arthritis itself does not directly involve the lymph nodes.

Shared Risk Factors

However, rheumatoid arthritis shares several risk factors with other autoimmune diseases that may impact lymph nodes, such as:

• Genetics
• Environmental triggers
• Hormone changes
• Chronic stress

The same factors that increase someone's vulnerability to developing rheumatoid arthritis may also increase susceptibility to lymph-related conditions.

Medications

Medications used to treat rheumatoid arthritis can sometimes also cause swollen lymph nodes. Methotrexate and anti-TNF biologic drugs may cause mild lymph node enlargement in some cases.

If swollen occipital lymph nodes develop while taking any rheumatoid arthritis medications, consult a doctor to rule out medication side effects, infections, or other complications that may require changing treatments.

When to Seek Emergency Care

In most cases, swollen occipital lymph nodes will resolve on their own or with treatment of the underlying condition. However, seek prompt medical attention if you experience:

• Severely enlarged nodes
• Nodes that are rapidly enlarging
• Nodes that feel very hard or immobile
• Swelling accompanied by high fever, headaches, or weight loss
• Facial swelling
• Difficulty turning head or swallowing

These signs may indicate a more serious infection or medical issue needing further evaluation and treatment.
