Swelling due to any kind of injury is the body's way of dealing with the trauma it has been subjected to. For any case of swelling, it is important to remember the rule of R-I-C-E. This would be translated as rest, ice, compress and elevate. The most important thing to bring down your swelling is to rest. Cold compresses will also help fight inflammation further. Keep your feet elevated above the level of your head in order to further reduce the swelling.
Among the other more effective remedies you can use at home to take care of a swollen ankle is to make a poultice of grated cucumber and raw potato and mix it with enough oil to make a paste. Apply this to your foot and leave it on till it dries. It has the ability to draw out pain from the foot and thereby provide relief. You can also rub the area with arnica tincture, which is considered miraculous for healing inflammation of all kinds. Soak your feet in hot water with a cup of salt thrown in. This will draw out the pain, reduce the swelling and give relief. You can also gently massage the tender area with olive oil to help you take care of the pain.
