Leg Swelling

Leg Swelling: Introduction

Leg swelling is an abnormal condition and a symptom of a variety of mild to serious diseases, disorders and conditions. Leg swelling, also called edema, can result from infection, inflammation, trauma, and circulatory disorders and cardiac disorders and other abnormal processes.

Depending on the cause, leg swelling can be short-term and disappear quickly, such as when it occurs due to sitting during a long airline flight. Chronic leg swelling often indicates a potentially serious disorder, such as congestive heart failure. Other serious conditions that can cause leg swelling include blood clots (deep vein thrombosis), kidney disease, preeclampsia, or liver disease.

Leg swelling can be the result of a wide variety of other conditions, diseases or disorders. These include orthopedic conditions, such as bone fractures, or a cast that is too tight. For more details about causes, see causes of leg swelling.

Leg swelling may occur with or without pain depending on the underlying disease or disorder that causes it. There are many other symptoms that can accompany leg swelling. Symptoms can include paresthesia, leg weakness, decreased range of motion and shortness of breath.

Diagnosing leg swelling and its root cause begins with taking a thorough personal and family medical history, including symptoms, and completing a physical examination, including a neurological examination. This includes testing a person's gait, reflexes, muscle strength and sensation.

Injuries to the leg that cause leg swelling, such as fractures, can often be diagnosed with an X-ray. Ligament and tendon injuries can be diagnosed using MRI.

A serious blood clot in the leg, called deep vein thrombosis, are diagnosed using a combination of the blood test called a D-dimer and ultrasound imaging.

Congestive heart failure is diagnosed using a variety of tests and exams. These include listening with a stethoscope to the sounds that the heart and lungs make. Certain lung sounds, such as a bubbling or crackling sound, point to congestive heart failure. Certain abnormal heart sounds can also increase the suspicion of congestive heart failure. Other tests include an EKG, chest X-ray, echocardiogram, stress test, angiogram and a blood test called a B-type natriuretic peptide (BNP).

Preeclampsia is diagnosed by regularly checking the blood pressure for hypertension and testing a woman's urine for protein during pregnancy.

A diagnosis of leg swelling and its cause can easily be delayed or missed because it can be mild or not last for long periods of time. For information on misdiagnosis, refer to misdiagnosis of leg swelling.

Some conditions can be easily and successfully treated and cured, while others may require more intensive treatment and may not have an optimal prognosis.
