Foot swelling is characterized as the accumulation of fluid in the foot. The buildup of excess fluid in any part of the body is called edema. The entire foot or only a region appears bigger than normal. The swelling might be painless or accompanied by various symptoms including itchiness, bruising, pain, redness, numbness, tenderness and stiffness.
The foot swelling might be an indication of an injury or condition affecting the foot or the entire body. The severity of the swelling depends on the underlying cause. The length and course of the swelling varies widely depending on the cause. The swelling due to injury often has an abrupt onset. In some cases, foot swelling from an underlying condition develops slowly and worsens over time.
