My Son Has Had Surgery On Both Ears. One To

My son has had surgery on both ears. one to remove a cyst the other to repair a hole in the ear drum that tubes cause when fluid built up behind them. He is having ear pain, headache, and is nauseous. Also says his equilibrium is off. Is there anything I can do for him at home. He's a senior in high school and has exams the rest of the week. I want him to be at his best.
