does this happen to anyone else?

for the last couple of days after driving (no matter the distance) i get out of the car and try to bend my right knee and there is a moderate to severe pain on the front left side of my knee...it seems to become less painful after i try to walk around for a bit but today it is still sore and i have been out of the car for about an hour....

any ideas?
