No need to apologize. We were all newbies once and full of questions.
My lower back pops or cracks from time to time. Sometimes it's audible, sometimes it's more a sense of "hearing" it from within myself, if that makes sense.
Most of the time when it pops it's when I move after I've been still for a good while. Also it sometimes pops when I'm getting dressed in the morning.
