Both of my knee's have cracked and popped constantly for years. Now it's progressed to my left knee "locking" up on me. It's happened about 4 times this last year. The locking up always happens when I am sitting with my knee bent. My knee gets stuck in a completly bent position for hours, its agony even trying to straighten it out a little (it feels like the WORST charlie horse/ tighness/cramping EVER!). I feel the muscle/tendon (not sure what it is maybe my Quad) sticking out through the back of my leg where it meets the back of my knee. After a few hours I just get frustrated and force myself to straighten it which is not fun at all.... but it feels like some thing snaps back into place and the pain is gone. I know I should see the Doc but I wanted to know if anyone else out there has had this happen. WHAT IS IT!? It's scary!
