### input:
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?

### output:

Hi, Ideally X-Ray should be done of the affected knee joint just to be sure that the bones are ok, because sometimes even a small displaced crack manifests with pain and difficulty in ambulation only. As far as swelling is concerned, it could just be an organized hematoma, but my concern is that if there is a significant hematoma over the joint, it usually suggests a significant soft tissue injury inside the knee joint which can be meniscus or a Ligament injury, so ideally 3 weeks of Rest and Ice packs and even after that your symptoms are still there kindly visit your Orthopedic specialist and get necessary investigations done. Till that time as I have mentioned. - Ice Packs 3-4 times a day- Compression bandage- Anti-inflammatory medication along with medicine to reduce swelling. Hope I have answered your query. Let me know if I can assist you further. Take care
