i have this and have done for around 4 years. I am now only 14 years old! so its not only older people who get it! i went to the docs about a year after it started and he said that many people just have joints that crack and that it is nothing to worry about
Im 20 and even before I could talk I would fall down screaming and crying from knee pain. I would get knee aches all the time when I was growing up and all the doctors said was it from me going through growth spurts. Well I went through my final growth spurt at 14 and my knees started popping and grinding. Since then they have gotten worse. Im in severe pain all the time. I can't be on my feet long, I can't do any exercises involving my knees, and when I bend my knees they pop and grind so loud people can hear them across the room. Just a few days ago I bent down and heard a shattering like sound from my right knee and now I can bearly walk...I get pain from deep inside my kneecap, below it, and on either side. It feels like my knee is jaming out of the sides but it looks normal. Im very afraid that im going to end up having to have surgery or something .
