I Have A Severe Pain In My Back On The

I have a severe pain in my back on the right side of my spine in my thoracic region, it has been getting progressively worse this past few months, I had an MRI and was diagnosed with Osteopaenia, its particularly bad when I stand for a period of time, \i dont think it can be anything too sinister but I am worried in case there is something wrong with my spine, do you think it could be caused by muscles being tight or is it something else
