Suggest Treatment For Chronic Thoracic Back Pain
Recent MRI is worse than first, surgery may be considered.
Detailed Answer:
I read your question carefully and I understand your concern.
The recent MRI is not good news, it does indeed show an increase in the degenerative changes in the spine, with impending compression of the spinal cord (fortunately no changes of the spinal cord which could cause neurological deficits).
So the question at this point is how to manage pain. generally it is preferred to avoid surgery and try to handle it conservatively. However in your case you seem to have exhausted conservative means, you have tried pain killers, steroid shots, rhizotomy. I suppose you have tried physical therapy as well. So at this point as usual options have been tried and failed yours is a case in which I would consider surgery for the disc herniation.
Of course after surgery physical therapy should be continued.

Detailed Answer:
Sorry for answering a little late, due to time difference the notification for your answer had come just as I had gone to sleep.
Regarding your question, naturally every surgery done under general anesthesia entails some risks, depending on patient's age and other medical conditions, such risks are minor but present in any patient independently from the type of surgery.
As for thoracic procedures, while it is true that cervical or lumbar disc herniations are much more common, the success rate remains high (figures may vary among studies but remain similar in that over 75% of patients are satisfied with outcome).
