Do I have a sprained knee?

Is my knee broken or sprained/strained?

• Okay well, yesterday a truck nearly hit me while i was on my bike and i tripped on a curb and fell. I have burns and scrapes but what is really worrying me is my left knee. It hurt A LOT yesterday, today it is bruised and swollen. it was very swollen in the morning when i woke up though. it looks round and different from my right knee. I can barely bend it only the slightest. no more than around 45-90 degrees or it will start hurting. It looks like someone implanted a ball in my knee and when I DO try to bend it, the middle left bit of my bone sticks out. that's were it hurts the most. the pain isnt very sever. Its not like i cry everytime i bend my knee but it hurts. Also sometimes when i walk, (limp) i can feel it popping. I dont know what to do and I dont want to push my parents to take me to the doctor until i am 100% sure of what is wrong with it. The reason for this is that the situation right now isnt exactly the best.. Oh and i dont have a bandage at home or anything like that. Pleasr answer quickly!!! its 1:30 at night and i need to sleep but i want to know what is wrong with my knee before I do pass out. And please, serious answers . Thank you sooo much x when i fell off my bike, i couldnt get up . I couldnt move my knee AT ALL... It hurt severly then but after 5 mins it still hurt severly but i managed to move my knee.. also could you please say what is WRONG with my knee thanks x The pain is mild when i bend it.. Please can someone tell me what this injury is called or what is possibly wrong. Please dont jump to, go get an xray! I need to know what is wrong first. thanks x

• Answer:

  I think you have possibly broken one bone in your knee, or you may have fractured it, ask your parents about the doctor:)My wrist was broken and it had swollen up and it felt numb. Good luck
