I've noticed that over the past year my bones, all over my body, pop a lot more. My back pops when I stretch it a little, it didn't to that before unless I deliberately tried to pop it. My feet pop when I take the first couple of steps after sitting for a while or getting out of bed. Is this normal or is there some kind of deficiency?

Differs between people. No orthopaedist will tell you, based on no symptom besides popping/clicking, that there is a problem. It generally just happens as we age. It sucks and is annoying, but that's that.

I have the same problem....and I'm 18.

A physical therapist told me that if you build your muscles, they will pull your bones into their proper place, negating chiropractors. I pop occasionally as well, but generally find the pops oddly enjoyable. Could just be your muscles putting things in place.

My knees sound like popcorn when I squat down and I can feel/hear a 'crinkling' sound in my knees when I am walking up stairs. The popping has been there forever, but the crinkling is new. I'm not much on running, but I do ride a bike quite a bit. Never have experienced pain.

Google is your friend.

"Two separate and distinct sources are responsible for the familiar popping sounds our joints emit.

The sound heard when our knuckles crack, results when a finger joint is extended almost to the end of its range. The joint, surrounded by a lubricating fluid, is encased in a capsule. At times, we intentionally, or unintentionally, extend the joint so far that the gas dissolved in the fluid spontaneously separates from the solution, forming a small bubble, and making a cracking sound. Not until the fluid reabsorbs the gas can the sound be reproduced. Whether or not there is truth to the old wives tale, that cracking ones knuckles enlarges them, remains open to debate.

On the other hand, the sound produced when we do deep-knee bends, is a snapping sound, produced when our tendons, which are merely the fibers that connect muscles and bones, elastically snap into new positions as our joints move under stress. Because the tendons shift back and forth with the movement of the joint, there is no waiting time before this snapping sound can be reproduced."

I can confirm this anecdotally. If I keep on top of my stretching and use of the foam roller, my knees and shoulders don't pop/crack. I don't think getting stronger has anything to do with it.

Is there anything bad about it?

I notice it moreso while doing squats.

I have two knees (I bet you do, too). One of them bothers me and the other is perfect but both crinkle exactly the same amount.

It doesn't hurt or anything....but having seen someone blow their knee out....it is one of my fears.
