I recently found out spinal problems run on my father's side (blood side).I have been having back problems fopr awhile,along with balance problems and circulation problems.I've had several types of tests done,including 2 seperate MRIs called for by a neurologist I was seeing.They came back as read the first time with no problems.But after having someone else(a professioal)read them,he said I should have a thoracic lumbar MRI,and a whole body sagital done,because there most likely is fluid build up.Anybody have any suggestions?

Yes, GET IT DONE ASAP! Fluid build up on the spine is nothing to take lightly, trust me with this 1!

Could be Syringomyelia? I've had it for years and no problems yet. But it scares the crap out of me.
