What is the best treatment for a soft tissue injury?

My friend is a physio. He says the old RICE thing is a bit old now. For a new injury, you should protect it for one or two days. But you should not rest it completely. Gentle movement is very important for healing. It helps blood flow. You can use some ice for the pain at first, for sure. A tensor bandage can help with swelling too. The most important thing is to slowly get back to your normal activity. Listen to your body. If it is a bad one, you should go see a doctor or a physiotherapist, eh?
