Lymph Node Health Checks

Lymph nodes are small, bean-shaped glands found throughout the body, including the neck, armpits, chest, abdomen, and groin. They are a vital part of the immune system, acting as filters that trap and destroy bacteria, viruses, and abnormal cells. Lymph nodes also produce and store white blood cells (lymphocytes), which help fight infection.

Common Lymph Node Conditions

• Reactive lymph nodes – temporary swelling in response to infections such as colds, sore throats, or skin infections
• Chronic inflammation – long-term enlargement due to autoimmune conditions or repeated infections
• Lymphoma – a cancer of the lymphatic system, which may present with persistent, painless swelling
• Metastatic disease – when cancer spreads from another part of the body (e.g., breast, lung, or melanoma) to the lymph nodes
• Abscess or infection – lymph nodes can fill with pus or fluid in severe bacterial infections

Symptoms of Lymph Node Problems

Symptoms may vary depending on the underlying cause and location of the affected lymph nodes.

Common signs include:

• Persistent or painless swelling in the neck, armpit, or groin
• Tender or painful nodes (often linked to infection)
• Hard or irregular nodes that don’t reduce in size
• Fever, night sweats, or unexplained weight loss
• Fatigue and low energy
• Recurrent infections or reduced immunity

Why Lymph Node Health Matters

While swollen lymph nodes are often harmless and linked to infections, persistent or unexplained changes may point to underlying conditions that require medical assessment.
A lymph node ultrasound provides a safe, accurate way to detect abnormalities early and guide further investigation if needed.
