Do you need to see a doctor for leg swelling?

If you have sudden swelling accompanied by shortness of breath, pain, difficulty walking, chest pain, or coughing, please seek medical care immediately. If the swelling develops gradually, it could be related to a chronic issue like venous insufficiency, but it’s still wise to get a medical evaluation to understand the cause.
