Ice, Ice, Ice
To help reduce inflammation, use ice to relieve pain in the first 48 hours following an injury. Ice can be applied for 20 minutes on, 20 minutes off.
After 48 hours you can try alternating between ice and heat. Again, stick with the 20 minutes on, 20 minutes off approach.
Alternating ice and heat is a great way to help reduce inflammation and regain range of motion.
