Hi. By upper & middle back I hope you mean thoracic pain.
If I may ask is your pain radiating along the chest wall in front?
Your previous MRI doesn’t comment anything about thoracic spine & if your pain is very severe & debilitating then you may need an urgent MRI, but if your pain is getting better with medicines then we can wait & watch. But to give a final conclusion we may need more details.

Should consult an expert.. will be happy to help.
