Red flags & when to go in person for Swollen Lymph Nodes

Audience: adult

Swollen lymph nodes are often a sign your body is fighting an infection or inflammation. They usually appear as lumps under the skin in areas like the neck, armpits, or groin. Many times, swollen lymph nodes are harmless and improve on their own. Telemedicine can help you understand your symptoms and decide if you need further care. However, some signs suggest a more serious issue that requires in-person evaluation. These include persistent swelling, pain, fever, or other concerning symptoms. Knowing when to seek in-person care is important to ensure proper diagnosis and treatment. This guide explains common causes, red flags, and how telemedicine can support you safely.

Red flags — go in person / ER

• Swollen lymph nodes larger than 2 inches (5 cm) or rapidly growing — seek in-person evaluation promptly.
• Persistent swelling lasting more than 2 to 4 weeks without improvement — see a healthcare provider in person.
• Associated symptoms such as high fever, night sweats, unexplained weight loss, difficulty breathing or swallowing — seek urgent in-person care.

What telemedicine can do

• Initial assessment of swollen lymph nodes and related symptoms.
• Providing advice on symptom monitoring and home care.
• Determining if symptoms require urgent in-person evaluation.
• Follow-up consultations for mild or resolving symptoms.

What telemedicine cannot do

• Physical examination to assess lymph node characteristics (hardness, fixation).
• Diagnostic procedures like blood tests, imaging, or biopsy.
• Management of severe infections or suspected cancers.
• Emergency care for airway obstruction or severe systemic symptoms.

What Are Swollen Lymph Nodes?

Lymph nodes are small, bean-shaped structures that help your immune system fight infections. When they swell, it usually means your body is responding to an infection or inflammation nearby. Common areas where you might notice swollen lymph nodes include the neck, under the arms, and groin.

Common Causes of Swollen Lymph Nodes

Swollen lymph nodes often result from infections such as colds, flu, throat infections, or skin infections. Other causes include allergic reactions, immune system conditions, or sometimes more serious conditions like cancers. Most swollen lymph nodes due to infections get better on their own within a few weeks.

When to Use Telemedicine for Swollen Lymph Nodes

Telemedicine can help you discuss your symptoms with a healthcare provider remotely. It is useful for initial assessments, monitoring mild symptoms, and getting advice on home care. During a tele-visit, your provider may ask about the size, location, and duration of swelling, as well as any other symptoms like fever or weight loss.

Can telemedicine diagnose the cause of swollen lymph nodes?

Telemedicine can help assess your symptoms and guide you on next steps, but it cannot replace physical exams or tests needed for a definitive diagnosis.
