Evert part of your bidy is important but your knees are one pf the most important ones. Once you lose your ability to walk without pain your life becomes misarable. I know this from my experices. I tore my ACL (anterior cruciate ligament) 4 times, twice in each knee palying basketball. Now I can't even run around the block.
It is good that you are seeking advice. But you are at the wronf place. I agree with the above posts but you need to see a doctor to get a professioanl advice. Sometimes minor injuries can lead to major ones.
