[|Human|] Hi! My daughter fell and hit her knee on our driveway last week. She went straight down on the asphalt really hard. Her knee was bruised, swollen and extremely painful. It is not feeling any better. She is having trouble walking and it hurts to straighten it out. Should she have an x-ray at this point. She saw her doctor two days after it happened, and he said to wait a while and then get an x-ray if it does not get better. I am worried she may have done some damage in there. She is 9 years old. Thank you!
[|AI|]  Hello, I read carefully your query and understand your concern. The symptoms of the child seem to be related to the injury of the knee. I suggest doing the x-ray of the knee for further evaluation. Meanwhile, I suggest using Ibuprofen to relieve the pain. I also suggest using cold compresses for local application. I recommend the rest and maintain the knee immobilized. Hope my answer was helpful. If you have further queries feel free to contact me again. Kind regards!  Chat Doctor.
