Overview
Leg swelling, especially around the ankle by the end of the day, can be related to venous disease. It can also come from other medical causes, so evaluation matters.
Common symptoms
- Ankle swelling by evening
- Sock indentations
- Heaviness or tightness
- Better after elevation
Why it happens
Venous reflux can increase pressure inside leg veins, contributing to fluid buildup in the surrounding tissues.
When to seek evaluation
If swelling is persistent, one-sided, painful, or progressing. Sudden one-sided swelling, severe pain, chest pain, or shortness of breath needs urgent care — call 911 if symptoms are severe.
How we evaluate it
Medical history, exam, and ultrasound when vein disease is suspected.
Treatment options
Compression, walking, elevation, and EVLT, RFA, VenaSeal, or Varithena if reflux is confirmed.
Sudden one-sided swelling with chest pain or shortness of breath requires emergency care.
