Swollen feet and ankles are often caused by fluid buildup from prolonged sitting, standing, hot weather, excess salt, or minor injuries. In many cases, the swelling is temporary and harmless.
However, persistent or unexplained swelling may be an early sign of heart, kidney, or liver problems. Swelling in one leg, especially with pain, redness, warmth, chest pain, or breathing difficulties, requires immediate medical attention.
While swollen feet are often harmless, they can sometimes be the body’s way of warning that something more serious is happening.
