If you have pain anywhere in your body, tell yourself it will go away, because it will. Thinking about the pain in any way prolongs it. Using ice packs or heat is no match to what your own effectors can do. They heal, and ice or heat just comforts for a short time, while keeping your mind on pain. Don't think twice about this. Know that you are just as powerful as any animal. They don't have ice or heat, or doctors, and they heal fast. We were blessed with a consciousness that can heal us faster than any living animal.
