Hi and welcome,
I would like to help if i can but i'm not sure how your information could be associated with MS, though i admit to being a little confused....are you saying the sentence "my MRI showed a centimeter passion on T 1-12" is meaning "Back thorasic lessions"?
If it is i've never seen or heard of that sentence before in relation to spinal 'cord lesions', and 1 cm seems too small to run all the way from T1 down to T12, is there a typo or is that the sentence written on your MRI report?
You have evidence of structural spinal degeneration in your lumbar and cervical spine, could your thoracic spinal information also be in relation to degenerative disc issues?
Sorry for all the questions but i genuinely would like to understand and try to help if i can.......JJ
