Hi, I m a 31 female and I fell hard on my right knee a week ago. My knee immediately swelled all over, but especially on the right side--there was a bump a little larger than a golf ball. I could walk on it, though it was sore, and I immediately went home and iced it and elevated it. The next day was more painful, but, again, I could still walk. The swelling went down, and now, a week later, it s terribly bruised and still painful--especially when I touch it, try to kneel, and sometimes even bend it). My main concern is that there s a solid hard painful bump that s the size of maybe a large marble (?) right were the major swelling occurred. Do you think I just need to keep icing it, or should I see a doctor for an x-ray?
