can anyone explain to me what may b wrong with my knee?

I injured my knee about 2 years ago. when i messed up a front hand spring. now tonight i cant sleep because my knee hurts so bad. my doctor says there is nothing wrong but there has to be for it to hurt this bad. my knee cap area is a little bit swollen. can anyone help me?

my child had water in her knee once it could be infected so did you tell your doctor it is swollen? this may not have to do with your past knee problem....

Maybe it is related to what happened previously. but you need to rest it. Try to see the doctor again and let him see the swollen knee for more assessment.

What is you age? it might be one factor as well.

as the doctor told you nothing wrong so thers nothing wrong
i just would like to say try donate a blood plasma 3 times
if you are live in an arabian country i'll tell you do hojama for your knee
i think they do it here in USA recently but am not sure wher you can find it
(hojama ) mean take bad blood out from around your knee so your knee can have frish blood
and that can make it better
