General edema

General edema is swelling caused by excess fluid trapped in the body's tissues. It can affect any part of the body, but is most noticeable in the feet, ankles, legs, hands, and face. It can develop suddenly or gradually. Symptoms range from mild to severe, and may include pain, itching, or a feeling of tightness in the affected area. In severe cases, the skin may become stretched, shiny, and discolored. Treatment depends on the underlying cause.
