I Have A Mild Sprain From Using A Punching Bag

I have a mild sprain from using a punching bag while irritated. It hurt the day of, but not at all in my two days off work. Now I'm back at work, on day three since my injury, where I use two keyboards and three mice(emergency telecommunications) and it hurts. BAD. I'm locked in for the next several hours and I can tough it out. Obviously I'm going to be doing some hot/I've treatment. Is it too late in the game for a compression wrap? Will that help with the irritation from small movements?
