I slipped on a wet tiled bathroom floor and landed right on my right knee. It was very swollen and badly bruised but i was able to walk normally after icing it for a couple of hours. However, it's been about 2 weeks now and i still feel my knew a little swollen. I am constantly feeling tingling sensations and it goes down my inner calf down to my foot. It makes my leg feel tired and heavy even when i'm laying down. Down i touch my knee my skin feels extremely numb and tingly right at the bottomw of my knee cap. I didn't go to the hospital when i fell because like i said i was able to walk perfectly fine. What should i do?
