How Can Body Joints Crepitus Be Treated?

Hi, I was wondering if i should be concerned about my joints' health.Almost all of my joints except for my elbows do tend to make popping/crackling sounds. I heard that strengthening muscles will help reduce this problem. In turn, i do lift weights to strengthen them. I have read that if isn't painful than its not a problem. For some reason i can't really shake it out of my head. Should i seek professional help?
