When I googled SH I found an article about a baseball player who had herniated a thoracic disc. You can Google it because I can't give you the link SH rules. But here is part of the story with the DR's name removed.
“Although herniated discs are relatively common, Cooper is among 1 to 2 percent of individuals who suffer a herniated disc in his thoracic spine,” says Dr. *****. “This area of the spine located deep within the chest cavity is very challenging to access, especially when the herniated disc is directly in front of the spinal cord. The surgery we performed is only offered in few places throughout the world and it was David’s best hope of returning to baseball. It’s remarkable he’s made such a spectacular recovery.”
If you have a thoracic injury it's pretty interesting to read. Mine is crushed vertebrae but I think the percentage is about the same. No wonder I can't find anyone who will operate in Australia. In the article it says he would be living in intense pain without the surgery. He is a fit young athlete who must have been in great shape. I am so happy Drs are finally believing thoracic injuries are not necessarily stable and can be incredibly painful.
