Lymph node and gland examination

Swelling, pain, or tightness in the neck area can be a sign that it’s time for a neck lymph node examination. This simple diagnostic procedure helps determine the cause of the node enlargement—whether it’s a mild infection or something that needs more attention. At Dr Prlja Medical in Belgrade, the exam is performed by an experienced team trained in early detection of lymphatic changes. The procedure is quick, painless, and doesn’t require special preparation. If the swelling lasts longer than two weeks, doesn’t go down, or gets worse, it’s important to act early. Accurate diagnosis can prevent unnecessary worry or delayed treatment. Book your appointment with us and find out what’s causing your symptoms—quickly, precisely, and without long waits.

What are lymph nodes in the neck and why are they important?

Lymph nodes in the neck are part of the immune system. They are located on both sides of the neck, under the jaw, and behind the ears. Their main job is to filter lymph—a fluid that contains white blood cells, microorganisms, and waste from tissues. When the body detects an infection, the lymph nodes may temporarily enlarge in response to bacteria, viruses, or other harmful agents. This triggers the activation of T and B lymphocytes—key immune cells that help fight infections.

Lymph nodes also help detect and contain the spread of infection. They act like a “checkpoint” where lymph fluid must pass through. Swollen lymph nodes, especially in the neck, are often the first sign that the body is fighting an illness—either a local issue like a throat infection or a systemic condition such as a viral infection, mononucleosis, or HIV. Their location near the respiratory and digestive tracts makes them vital for early detection of related health problems.

Symptoms that indicate it’s time for a neck lymph node examination

Lymph nodes in the neck may respond to different processes in the body, but some symptoms call for an ENT evaluation. If swelling is present without a fever or cold, an exam can help rule out more serious causes. Slight enlargement up to 1 cm, especially if soft and movable, is often normal. Swelling after an infection may last up to four weeks without other symptoms. A timely medical check is advised if you notice any of the following:

• A hard, painless lymph node: May signal long-term immune activity, chronic infection, or cell proliferation, as seen in some blood or cancer-related conditions.
• Unexplained weight loss: Can occur in systemic diseases like lymphoma, where the immune system consumes more energy.
• Night sweats: Often result from inflammatory cytokines or changes in the body’s temperature control due to active immune response.
• Fever without a clear cause: Could mean the immune system is reacting to antigens in the lymph nodes, triggering inflammation without an obvious infection.

After an infection, lymph nodes may stay enlarged for a while. If swelling lasts beyond three to four weeks with no sign of improvement, medical evaluation is recommended.

In children, firm, large, or asymmetrical swelling—especially with symptoms like fatigue or persistent fever—requires further testing. Our medical team carefully evaluates each case and offers clear guidance on what to do next.

How to tell an enlarged lymph node from other neck-area skin changes

It’s important to distinguish an enlarged lymph node from other subcutaneous or skin changes in the same area:

• Lipomas are soft, fatty lumps under the skin. They move easily under the fingers but do not respond to infections.
• Atheromas form when sebaceous glands become blocked. These lumps are often accompanied by redness or skin inflammation.
• Enlarged salivary glands, especially submandibular ones, can cause swelling under the jaw. However, they differ in texture and clinical presentation.

Some surface skin changes can also be mistaken for deeper tissue swelling. These include:

• Actinic keratoses are rough, superficial lesions found only on the skin, not in deeper tissues.
• Viral warts have a bumpy surface and usually appear above skin level, with no connection to the lymphatic system.
• More prominent moles are clearly defined, pigmented spots. They do not move and do not change with touch, unlike lymph nodes, which are located under the skin.

During an exam, the doctor carefully distinguishes these from lymph nodes using palpation, visual assessment, and, when needed, additional testing.

What does a neck lymph node exam involve?

A neck lymph node exam is a clinical assessment where the doctor checks by palpation:

• size
• consistency
• mobility
• tenderness of the nodes
• their relation to nearby structures

If a more detailed view is needed, an ultrasound of the neck lymph nodes is performed. This is a non-invasive, painless method that shows the internal structure, shape, borders, and blood flow of the node.

A quick evaluation helps identify common reactive, harmless changes early and distinguish them from those that need further testing, reducing the risk of missing serious conditions. The most common causes are infections or localized inflammation. The presence of lymphadenopathy does not automatically mean cancer such as lymphoma or metastases. These conditions have distinct features, assessed through clinical exams and ultrasound—not assumptions or fear. Our team provides a calm, expert approach to help you get clear answers without delay.

What the exam can reveal and how the doctor decides on next steps

During a neck lymph node exam, the doctor evaluates whether the changes are reactive, meaning harmless. These are usually linked to mild viral or bacterial infections. Reactive changes—caused by a local or systemic infection—typically appear as nodes that are:

• smaller than 1 cm (or up to 1.5 cm in the submandibular area)
• soft in texture
• movable
• tender to the touch

Such findings usually resolve on their own without treatment.

On the other hand, if your body is dealing with underlying conditions such as chronic infections, granulomatous diseases, or blood disorders, these can appear as enlarged lymph nodes that are:

• hard
• immobile
• painless
• gradually increasing in size
• Asymmetrical swelling, especially in the supraclavicular area, requires more attention, as this location may indicate systemic issues.

What happens after the exam?

The doctor also considers how long the swelling has lasted. If a hard, painless node remains unchanged for more than 3–4 weeks, lab tests are usually advised:

• complete blood count
• CRP
• ESR
• serological and hormonal testing (including thyroid tests)

If there’s no concern for a serious condition and the node is stable, a follow-up exam in 2 to 4 weeks may be recommended, along with monitoring symptoms at home.

In cases where the nodes are symmetrical, small (<1 cm), soft, movable, and tender, and the patient has no other symptoms, no further testing is needed—just observation. Our team explains all findings clearly and gives guidance based on clinical recommendations.
