My right knee has always been giving me slight pain from time to time. And I had a big cut on it the last month playing court soccer.


This time, I injure my left knee while roller-blading. There's a pain during movement in the knee and it feels uncomfortable. And I took a look at it just now, there's a swell at the knee cap. I hope it's not too serious. I'll give it 1 day to get better before going to the doctor...
