Swollen lymph nodes, also known as lymphadenopathy, occur when the body’s lymph nodes become enlarged. Lymph nodes are small, bean-shaped structures located throughout the body that help fight infection and disease. They contain immune cells that filter out bacteria, viruses, and other harmful substances from the lymph fluid. When the body is fighting an infection or disease, the lymph nodes can become swollen and tender as they work to trap and destroy the invading pathogens.
Checking for swollen lymph nodes is an important part of a physical examination. It can help identify infections, diseases, or other medical conditions that may require treatment. There are several areas of the body where lymph nodes can be easily felt, including the neck, armpits, and groin. To check for swollen lymph nodes, use your fingers to gently feel for any lumps or bumps in these areas. If you find any swollen lymph nodes, it is important to see a doctor to determine the cause and receive appropriate treatment.
Here are some tips for checking for swollen lymph nodes:
- Use your fingers to gently feel for lumps or bumps in the following areas:
- Neck
- Armpits
- Groin
- If you find any swollen lymph nodes, note their size, shape, and location.
- If the lymph nodes are painful or tender, or if you have any other symptoms, such as fever, chills, or body aches, see a doctor promptly.
1. Location
When checking for swollen lymph nodes, it is important to be aware of their location throughout the body. Lymph nodes are small, bean-shaped structures that are part of the lymphatic system, which helps to fight infection and disease. They are located in clusters in various areas of the body, including the neck, armpits, groin, chest, abdomen, and pelvis.
The most common areas to check for swollen lymph nodes are the neck, armpits, and groin. This is because these areas are easily accessible and contain a large number of lymph nodes. To check for swollen lymph nodes in these areas, use your fingers to gently feel for any lumps or bumps. If you find any swollen lymph nodes, note their size, shape, and location. If the lymph nodes are painful or tender, or if you have any other symptoms, such as fever, chills, or body aches, see a doctor promptly.
Knowing the location of lymph nodes is important for checking for swollen lymph nodes because it allows you to identify areas that may be affected by infection or disease. By being aware of the location of lymph nodes, you can also be more proactive in monitoring your health and seeking medical attention if necessary.
2. Size
The size of lymph nodes is an important factor to consider when checking for swollen lymph nodes. Normal lymph nodes are usually small, about the size of a pea or bean. Swollen lymph nodes may be larger, ranging from the size of a grape to a ping-pong ball. This enlargement can be a sign of infection, disease, or other medical conditions.

Facet 1: Lymph Node Enlargement and Infection
One of the most common causes of swollen lymph nodes is infection. When the body is fighting an infection, the lymph nodes in the affected area will often become enlarged as they work to trap and destroy the invading pathogens. This enlargement can be a sign of a variety of infections, including bacterial infections, viral infections, and parasitic infections.
-
Facet 2: Lymph Node Enlargement and Disease
Swollen lymph nodes can also be a sign of disease. Some diseases, such as cancer, can cause the lymph nodes to become enlarged. This enlargement can be a sign of the disease itself or a sign that the disease has spread to the lymph nodes.
-
Facet 3: Lymph Node Enlargement and Other Medical Conditions
Swollen lymph nodes can also be a sign of other medical conditions, such as autoimmune disorders and allergic reactions. In these cases, the lymph nodes may become enlarged as part of the body’s immune response.
It is important to note that not all swollen lymph nodes are a cause for concern. However, if the lymph nodes are large, painful, or accompanied by other symptoms, such as fever, chills, or body aches, it is important to see a doctor promptly.
3. Shape
The shape of a lymph node can be an important factor in determining whether or not it is swollen. Normal lymph nodes are typically round or oval in shape. Swollen lymph nodes may be round, oval, or irregular in shape. This change in shape can be a sign of infection, disease, or other medical conditions.
One of the most common causes of swollen lymph nodes is infection. When the body is fighting an infection, the lymph nodes in the affected area will often become enlarged as they work to trap and destroy the invading pathogens. This enlargement can cause the lymph nodes to become irregular in shape.
Swollen lymph nodes can also be a sign of disease. Some diseases, such as cancer, can cause the lymph nodes to become enlarged and irregular in shape. This enlargement can be a sign of the disease itself or a sign that the disease has spread to the lymph nodes.
In addition to infection and disease, other medical conditions can also cause swollen lymph nodes. For example, autoimmune disorders and allergic reactions can cause the lymph nodes to become enlarged and irregular in shape.
It is important to note that not all swollen lymph nodes are a cause for concern. However, if the lymph nodes are large, painful, or accompanied by other symptoms, such as fever, chills, or body aches, it is important to see a doctor promptly.
4. Tenderness
When checking for swollen lymph nodes, it is important to assess their tenderness. Normal lymph nodes are usually not tender, meaning they do not cause pain when touched. However, swollen lymph nodes may be tender or painful when touched, which can be a sign of infection or disease.
-
Facet 1: Tenderness and Infection
One of the most common causes of swollen and tender lymph nodes is infection. When the body is fighting an infection, the lymph nodes in the affected area will often become enlarged and tender as they work to trap and destroy the invading pathogens.
-
Facet 2: Tenderness and Disease
Swollen and tender lymph nodes can also be a sign of disease. Some diseases, such as cancer, can cause the lymph nodes to become enlarged and tender. This enlargement and tenderness can be a sign of the disease itself or a sign that the disease has spread to the lymph nodes.
-
Facet 3: Tenderness and Other Medical Conditions
In addition to infection and disease, other medical conditions can also cause swollen and tender lymph nodes. For example, autoimmune disorders and allergic reactions can cause the lymph nodes to become enlarged and tender.
-
Facet 4: Tenderness and Importance in Checking for Swollen Lymph Nodes
Assessing the tenderness of lymph nodes is an important part of checking for swollen lymph nodes. Tenderness can be a sign of infection, disease, or other medical conditions. By assessing the tenderness of lymph nodes, healthcare professionals can better determine the underlying cause of the swelling and recommend appropriate treatment.
It is important to note that not all swollen and tender lymph nodes are a cause for concern. However, if the lymph nodes are large, painful, or accompanied by other symptoms, such as fever, chills, or body aches, it is important to see a doctor promptly.
5. Mobility
When checking for swollen lymph nodes, it is important to assess their mobility. Normal lymph nodes are usually movable, meaning they can be moved back and forth when touched. Swollen lymph nodes may be fixed in place or matted together, which can be a sign of infection or disease.
One of the most common causes of fixed or matted lymph nodes is infection. When the body is fighting an infection, the lymph nodes in the affected area will often become enlarged and inflamed. This inflammation can cause the lymph nodes to become fixed in place or matted together.
Swollen, fixed, or matted lymph nodes can also be a sign of disease. Some diseases, such as cancer, can cause the lymph nodes to become enlarged and fixed in place. This enlargement and fixation can be a sign of the disease itself or a sign that the disease has spread to the lymph nodes.
In addition to infection and disease, other medical conditions can also cause swollen, fixed, or matted lymph nodes. For example, autoimmune disorders and allergic reactions can cause the lymph nodes to become enlarged and fixed in place.
Assessing the mobility of lymph nodes is an important part of checking for swollen lymph nodes. Fixed or matted lymph nodes can be a sign of infection, disease, or other medical conditions. By assessing the mobility of lymph nodes, healthcare professionals can better determine the underlying cause of the swelling and recommend appropriate treatment.
