<human>: I fell hard on my knee and I have a deep contusion; it's really painful. I went to the hospital last night for x-rays, and showed no fractures, however the doctor gave me a work restriction for four days, and told me to keep my leg up and stay in bed. This isn't exactly working for me. I don't have a desk job, and am responsible for my department, however I am doing my best to stay off my feet.
For pain I was told to take 600mg advil, and 2 tylenol 3, but he was very brisk, and I forgot to ask him how often I could do this.
Is it safe for me to take more of either one?
