Do you need to see a doctor for leg swelling?

If the swelling is sudden and associated with shortness of breath, pain, difficulty walking, chest pain, coughing, seek medical care immediately. Swelling that progresses slowly over time is more likely related to a chronic issue such as venous insufficiency, but it is still prudent to have a medical evaluation to address the underlying cause of the swelling.
