Tele-triage for Swollen Lymph Nodes

Audience: adult

Swollen lymph nodes are common and often a sign your body is fighting an infection. They can appear in your neck, underarms, or groin. Telemedicine can help you understand possible causes and decide if you need further care. During a tele-visit, a healthcare provider will ask about your symptoms, medical history, and may guide you on self-examination. While many cases are mild and resolve on their own, some swollen lymph nodes require in-person evaluation. Tele-triage helps identify when urgent care is needed, such as if swelling is sudden, painful, or accompanied by other concerning symptoms. This guide explains what telemedicine can do for swollen lymph nodes, when to seek direct medical attention, and how to prepare for your tele-visit.

Common causes include colds, throat infections, or skin infections nearby. Swollen lymph nodes can feel like lumps under your skin and may be tender or painless.
