I had a Bone Scan done on 3/21/12 and my Doctors nurse just called aand said I have Osteoporis and my Doctor wants me on Actonel or Fossmax ASAP?? I had a compression fracture of my spine in 1988 from a horseback riding accident and I'm 4ft 81/2 tall 54 yrs. My question is the Nurse said my T-Score was -2.7 was does that mean?? Plain terms please. I can"t figure out the scoreing thing. not good at math.
