I am 27 years old male, my body has legs and neck, back muscles strained when it is stretched, then it gets relaxes for few minutes with kradd. Such a sound. I have to do this often in the night and in the day. My body previously had a deficiency of vitamin b12 which is now ok and there are a few calcium deficiency presently. I also experiences such thing in brain. When I press the jaw and tweak it on the neck, it relaxes. So is there no end to this problem. What can I have trouble with?
