I WAS RIDING MY LAWNMOWER AND I ACCIDENTALLY HIT A

I WAS RIDING MY LAWNMOWER AND I ACCIDENTALLY HIT A LOG THAT IS LAYING IN THE YARD. THE FORCE OF THE IMPACT CAUSED MY HAND TO PUSH AGAINST THE STEERING WHEEL CAUSING MY WRIST TO BE STRAINED OR SPRAINED. I CAN MOVE IT BUT IT'S PAINFUL. I'M SURE IT IS NOT BROKEN. WHAT CAN I DO AT HOME TO HELP HEAL IT.
