What Are the Causes of Lower Leg Swelling?
Lower leg swelling can occur as a result of an injury or condition directly related to the leg or as a result of conditions that involve distant organs and affect the whole body. Inferences about the causes of leg swelling can be made based on the characteristics of the swelling. MayoClinic.com notes that if the swelling occurs in only one leg, it is usually a result of a condition that affects only the leg. If swelling occurs in both legs, it is most often a result of conditions that involve the organs.
