No, you are just popping little bubbles, it is fine.

If you keep cracking your back then it could be bad. But it wouldn't tell on you at a young age but when you get older it will.If it just crack with out anyone doing it to you or you doing it to your self no it's not bad
Crack is bad because it can cause health problems, addition, and other problems.
It's best to cut out the bad area and replace with new pvc, then glue back together.
When i crack my back i sit on the ground or a chair or something and just twist to the left and right, it cracks. You could also get someone to crack your back by them walking and pushing on your back.
It isn't good... But cracking knuckles and other joints doesnt cause any damage. However if you crack your neck and back, there is a possibility of pinching a nerve or straining a muscle so be careful.
i don't really no. if you move your hands and actually put force on it to crack it its bad but if you just stretch it and it cracks that's fine. but i would talk to a doctor or chiropracter
Yes, it is bad, and it ages you before your time.
