First game back after thumb sprain

any advice? I've taken 3 weeks off and the pain is mostly gone, but not completely. I'm going to wrap the thumb (spica) and warm up properly, but is there anything else i could/should do to protect it?

edit due to warning - I've had it looked at by a radiologist who advised it's fine, just sprained and sore. "you can play, but it will hurt if you get a thump" was his advice. my question is how I can avoid making it more sore pre or in game?
