R.I.C.E. stands for Rest, Ice, Compression, and Elevation. These steps can be used at home to treat hematoma on your arms and legs and should be practiced on a daily basis for the best results. Try to apply R.I.C.E. as soon as you develop the hematoma for optimal recovery and healing. Make sure you rest the affected area during the first 24–72 hours of developing the hematoma. This will prevent any further bleeding and allow the area to heal. Some physicians recommend that you rest a lower limb that has hematoma, such as your leg, for at least 48 hours. The duration of the rest period is dependent on the extent of the hematoma. Apply an ice pack wrapped in a towel, or perform an ice massage on the affected limb. This will decrease the pain and swelling of the hematoma.  To apply an ice massage, freeze a plastic foam cup of water. Hold the cup and place a cloth or paper towel over the affected limb, then apply ice. Never apply ice or an ice pack directly to skin, as this increases risk for a thermal burn or frostbite. After the first 48 hours, you can use a heated compress, such as a heating pad or a very warm washcloth, two to three times a day, to help your body reabsorb the blood from the hematoma. Use a compression wrap or a compressive elastic bandage over the hematoma until it appears less swollen. You can find compression wraps and compressive elastic bandages at your local drugstore or pharmacy.  You should maintain compression on the area for at least two to seven days. Make sure the compression bandage is on properly and it is snug, but not cutting off blood circulation to the limb. A wrap that cuts off circulation will trigger throbbing in the area or skin color changes such as becoming deeper purple or blanching entirely. This will help to reduce the pain and swelling. Raise the affected limb above the level of your heart on a chair or a stack of pillows. This medication will help with the pain and swelling you may experience as the hematoma heals.  Ibuprofen (Advil, Motrin) is a very effective...
