I was told x-ray does not do the job on telling you exactly what is wrong if anything is going on with you spine or back. get MRI
Have a nerve conduction test...found out most of my pain is from my static nerve ..also u properly have a torn rooter cuff..have had 6 rotor cuff surgeries , 3 on each shoulder ..once u get ur rotor cuff fixed u will be enjoying life again..
As the other two posters stated an x-ray won't find what you are describing. I would also suggest the MRI but it could be a rotary cuff issue as greataunty stated. I would consult your doctor on these options and see which one they suggest.
i asked the dr for an mri he said he would send me for a whole body ct scan but the showed every thing was fine also ..
i;ll find out a little bit more on that thanx meg
