If it's discogenic the options are to risk fusing it or wait for stem cell technology and see if u can get some benefit from that. You know better than anyone that many docs have trouble even believing that pain comes from thoracic discs.. unfortunately all that can be done is wait until medical technology proves them wrong... again.
U are too young to have this.. sorry I can't help with options in Croatia. I'm sure there are options that can be investigated internationally.. but v. expensive of course.
