However, most long-term effects are related to the cause. For example, liver, heart or kidney diseases can lead to serious disability or even death. Infections of a limb may go away completely and have no long-term effects. In severe cases, however, the limb may need to be amputated. Swelling of the limbs is not contagious and poses no risks to others.
Treatment is directed at the cause.
For example, an infection of a limb is usually treated with antibiotics. Swelling due to congestive heart failure is often treated with medications such as diuretics. Diuretics make a person urinate more. This often gets rid of extra fluid and decreases swelling. People with a deep venous thrombosis are often put on medications known as blood thinners or anticoagulants, to prevent complications and further blood clots.
