Not necessarily any connection between joint noise and anything else. Pain is worth having checked out, but absent any other symptoms I'd be inclined to a watching brief.
In my case I have a very clicky left knee, slightly less on the right, and the left will occasionally give way on me but painlessly. I ascribe it to years of rugby, and just see it as one of those things, symptoms not getting worse.
No harm in seeing a gp of course if youre worried about it.
