knees/legs ache...

[rookie03]

My knees and legs get this weird stretching aching feeling in them pretty frequently. alot of the time its only in my right knee. Even if i havent trained legs for that week, and it happens late nights alot too. Im just curious if anyone gets this, and maybe could shed some light on what the hell it is.

My legs are often sore, from heavy squats sometimes it is joint soreness and sometimes it is muscle soreness. It is the joint soreness that concerns me.
