It is important that if an area is injured or if there is excess inflammation to start icing it within the first 48 to 72 hours of the symptoms. Using ice on the injured area will help reduce any internal bleeding or swelling in the area caused by physical activity. It is important to start as soon as possible otherwise inflammation can set in and it will cause pain, swelling, redness, heat, and decrease function in the area, which is not good!When applying to ice to an injured area keep it on the area for 10 to 30 minutes at a time and then leave it off for 30 to 45 minutes. After the 30-45 minutes are up and if there is still discomfort, ice can be applied for another 10 to 30 minutes. Repeat this procedure for as long as necessary to help reduce any discomfort felt. When discomfort is felt in joints from overuse or another form of injury, ice should be applied for several times for the next 48hrs. If the area does not get any better seek medical assistance. Likewise a deep muscle injury will take longer to cool than a tendon/ligament injury so it would be best to ice for 48 to 72 hours to see if any pain or discomfort still persists. Also if a severe bruise happens to any part of the body the bruise will benefit from icing for up to 7 days after it is injured.
Do not directly put the ice on your skin, which may cause ice burn. It is best to have a ice bag or if not grab a plastic bag and wrap a towel around it and place the bag with the towel wrapped around it on the injured area. Also if the skin is numb you can stop the icing and let it warm up and then repeat if necessary. Do not use ice on open wounds or blisters. Remember if the area does not get any better after a couple days it would be best to seek medical attention to make sure the injured area is not severely hurt.Contrasting Showers
After taking a hot shower turn down the water to a temperature cool enough to tolerate for roughly 1 minute. If there are specific sore areas focus the stream of cool water on that area. After the one minute is up turn the water back to warm for 3-5 minutes. Make sure the warm phase is always longer than the cold phase. Repeat this cycle 3-5 times. Make sure to end on a cold phase.
