hi thanks for the reply,

I decided not to go to a+e lastnight and decided to take some painkillers and go to sleep, this morning my knee sweeling has reduced dramatically and i can curl my leg while standing using my hamstrings, and i am able to sit whereas yesterday i wasnt.

Is this symtoms of a Wikipedia reference-linkmeniscus tear?

I still cannot extend my leg from sitting though, do you think going straight to the local physio will be best thanks again aaron.
