Hi, I'm a very active person, volleyball, biking, hiking, running, weight lifting, etc. Never had knee problems
. Recently, my right knee
, when in the same position for a couple of minutes, straight or bent, kinda becomes stuck. It is very painful to bend if straight or straighten if bent. It wakes me up at night. I sleep with my knee bent and it wakes me when I move at all. It is excruciating pain to straighten it. But, once I'm up, I have no pain whatsoever. I walk a lot at work.
