Knee Click

I was walking down the stairs the other day and I heard a click in my left knee, just above my knee cap and something felt oddly wrong. I think I placed my foot slightly in one direction and the knee didn’t rotate correctly so there was that click. Later on as I was walking I felt some pain in my left knee, felt like shooting pain through my knee. Even when I was laying down something just felt odd about that joint, I wasn’t sure what was causing the pain but I could clearly feel it. Even when I would walk quickly it felt like my knee is going to bend in the other direction, and this is probably the weekend which I moved the least so I’m not sure what physical activity caused this little problem, but I know I need to get back in shape and this pain is ridiculously annoying.
