Answers: Maybe something with the lymphatic system (lymph nodes)
Or endocrine system (hormones)
Maybe bring her to a Chiropractor, Or someone else who specializes in problems of this nature, here may be something they can detect that won't show on an x-ray, or maybe the Her doctor or the Radiologist doesn't know exactly what they are looking for or just don't endorse something.
Get a second opinion.
A friend of mine had a posterior injury, one doctor told her all was in good health, after treatment(probably a surgery) she knew it wasn't, she went to another specialist surrounded by another town and got a second opinion. The second doctor told her the first guy wasn't reading her MRI correctly, in attendance still were things that needed fixing.
EDIT: perhaps it is a build up of spinal fluid or some other fluid related to the lymph or endocrine system SO. a fracture or dislocated disc isn't showing on an x-ray because they aren't here to show-up.
