Leg swelling does not always indicate a serious health issue, according to Healthline. However, in some cases it may be a symptom of an underlying health problem. If symptoms such as chest pain, dizziness, confusion, faintness or difficulty breathing accompany leg swelling, seek immediate emergency medical attention. Accompanying symptoms that require a non-emergency doctor's appointment include warmth or redness in the swelling areas and high body temperature.
Additionally, arrange a doctor's visit if leg swelling occurs while pregnant, gets worse, is not remedied by home treatment, or if already diagnosed with liver, heart or kidney disease. While speaking with a doctor, it is important to be able to describe when the swelling was noticed, time of day it gets worse, any additional symptoms, and if anything makes it feel better or worse, as noted by Healthline.
The most-common causes of leg swelling include being overweight, standing or being confined for long periods of time, and taking certain hormone supplements or antidepressants. Certain blood pressure medications, steroids and anti-inflammatory medicines also cause leg swelling, explains Healthline. Medical conditions that also contribute to leg swelling include changes during the menstrual cycle, pregnancy, blood clot or infection in the leg, injuries, and organ failure.
