This has begun recently and I guess I am just curious if there is something I can do to help it, or if anyone has any ideas why it is happening. Riding is fine, walking around or whatever is fine, but if I sit still for a period (like watching a movie or something) my knees start to ache. This has been going on for about a month I would say. They also make snap/crackle/pop noises when I move them but they have always done that. Also I'm 24 years old. What do you guys think?
P.S. I was going to post this in the health forum or something, but there isn't one, so that's good since this is the only forum I read anyways..
