did some squatting today, did 5 plates for 5 reps, on the 3rd rep went down too fast and leant forward abit so had to use back. when i finished my knee was killing when i bent it.
got home put ice on it, then had hot bath and its swollen up. it hurts at the bottom right hand side of right knee and swollen there too. feel fine to walk just when bend it very painful.

this sound bad or just rest for couple of days?
