There are no urgent problems with your bones.
Schmorl's nodes are not an immediate problem, but be careful because your back can't handle trauma. Sacralization of L5 is a minor birth defect, but very common and not very problematic.
Google Schmorl's nodes and then sacralization of L5 for descriptions.
thats one of my problems and Im having so much pain, but I also have scattered haemangiomas in vertibral bodies.Ive also bulged discs, weighted discs, axial weighted through discs, kyphontic changes, dessication of the thoracic and lumba discs, facetal changes and masses in my liver that need to be comfirmed with another scan.
