Knee pain

My knee pain's back to haunt me!! ITS BEEN FOR 3YEARS!!! Its all really due to the badminton and basketball playing. *dash underscore dash* That's why I wasn't able to run much or even jump while playing these sports. I can't bear the pain again. And that results in me suffering while walking up and down the stairs. Can't even wear high heels. I wonder when all these will end. I seriously don't want to end up undergo surgery to remove the menisci or what. And I soooo miss track-running where me and Ah Ong always compete against each other to see who's the fastest. =(
