Hello I had one car wreck about three weeks ago My knee hit the dashboard and put a dent in it ,,Well i waited to go to er and all the results come up neg go i went to my family doctor and she sent me for a MRI which showed I had broke my knee cap ,,And then went to a bone doctor well i still having pain but the weird thing is now the back of my leg si hurting i just wander if i could have messed something else up cause the doc told me it would heal on it on with no help just act normal seeing how the wreck was three weeks ago He said it should heal up in 2 to 3 weeks with no brace or anything Do u think i should get a second opinion....... :-|
