Tele-triage for Swelling in Legs (Edema)

Audience: adult

Swelling in the legs, also called edema, happens when fluid builds up in the tissues. It can cause discomfort and may be a sign of different health issues, from mild to serious. Telemedicine can help you understand possible causes and decide if you need to see a healthcare provider in person. During a tele-visit, a clinician will ask about your symptoms, medical history, and lifestyle. They may guide you on managing mild swelling at home or recommend urgent care if there are warning signs. However, some situations require in-person evaluation, such as sudden swelling, pain, or signs of infection. Knowing when to seek immediate care is important for your safety. This guide helps you prepare for a telemedicine visit about leg swelling and explains what telemedicine can and cannot do for this symptom.
