My name is X and I am a 19 year old from Eastern Kentucky. For nearly a year, I've been experiencing horrible pain in my right knee, the pain is usually located on the left side of my knee and on the lower part of my calf and my foot. When I bend it back and unbend it, my kneecap will painfully crack and it gets worse. My left knee sometimes does the same thing. Sometimes when I walk, it feels like I can barely put any weight on my right leg due to the pain. I also experience cracking whenever I walk too. I am also a very active person and tend to stay on my feet a lot. What could this be?
