First of all, hello to everyone on the board 
I started cracking joints when I was younger 12/13/14 or there abouts, it started with the knuckles and knees but has quickly spread to different parts of my body including my lower/upper back and my neck(these three are what I'm really worried about).
My spine is now a lot more arced and 'sticks out' a lot more and I often get lower back pain usually resulting in me cracking it. Likewise my neck seems to be 'sticking out' more and can become very tense at times. I tend to crack my back by either leaning back over a chair or twisting to each side, and my neck by either twisting it sidewards with my hand or pulling my head downwards.
So what I want to ask is, has anyone encountered these symptoms before and have you got any tips on how to stop cracking?
Thanks for your time.
