I have cracked my neck for many years probably once a day. I have just had an anxiety attack looking at what it can do to you if done wrong. I kinda push my neck to one side but resist at the same time and then it cracks. Can’t stop worrying now that allot of my head/neck tension could be due to that?! or am i overthinking.  I hear allot of people do it same with knuckles and toes and what not.
