I started to get a weird feeling in my right knee feeling as if it had to be stretched, 30 minutes later while in the shower I got another funny feeling in my right café to knee I looked down and it looked like around my knee bone was swollen, the pain is coming and going only now it goes up to my thigh and my toes start to tingle and I can not move my knee or toes.

Seriously, see a doctor ASAP.
