when it hurts constantly RIGHT behind your knee? not only does it constantly hurt but it doesn't even hurt alot.... just enough to be a noticeable pain in the ass. And if that certain feeling didn't have a bad enough reputation already it always seems that if ya get it in the morning its gone around mid-day. if ya get it around i dunno, say 5pm its pretty much with ya till ya sleep. then whilst trying to sleep ya can REALLY feel it cuz ur not really doin anything else to occupy you. Well, its annoying.... Thats all.
