[/INST] Hello samantha,  gap what some body has told you is not a problem.  All bones had a cushion in between which on  x rays looks like a gap.  What causing yproblem  is disc herniation.  It can be checked on mri only.  Treatment  is physiotherapy and drugs. Medicine  like myospaz and myoril are  helpful. </s>
