What happens during a sporting meniscus injury and does anybody have any experience?

[Langylfc9]

Hey im a very keen football an around 10-11 weeks ago i was running with the ball for my local an my knee jurked and my leg went one way and i went the onther. i was on the floor screeming in pain and went to hospital and had an x-ray and they saw nothin n was told to rest... weeks later i felt sightly better but knee still struggled to bend so i decided to play in a match for my team again dispite scoring 2 goals my knee popped again but sounded like a crunching sound... so rested again for around 4 weeks and then dicided to watch my team... and then i ran chasing a ball and heard that crunching sound again.... days later i went to the doctors and was told that i may have torn my meniscus in my knee and will need to have key hole sugery...
so what i want to know is what should i do and does anybody have any experience with this type of injury?? thanks :?)
