Foot, leg, and ankle swelling is also known as peripheral edema, which refers to an accumulation of fluid in these parts of the body. The buildup of fluid usually isn’t painful, unless it’s due to injury. Swelling is often more apparent in the lower areas of the body because of gravity.
Foot, leg, and ankle swelling is most common in older adults. The swelling can occur on both sides of the body or on just one side. One or more areas in the lower body may be affected.
While swelling in the foot, leg, and ankle usually doesn’t pose a significant health risk, it’s important to know when to see a doctor. Swelling may sometimes indicate a more serious underlying health issue that needs to be treated right away.
