MRI results in 2012: Disc protrusion and annular tear of the left T9-T10 neural foramina.

Since then, my back has "gone out" on several occasions. There are times when the pain is severe but it doesn't go out completely. Other times when it's not necessarily horrible pain but it feels like I am on the verge of losing all mobility.

It is still very localized to that main lower thoracic area so I'm left wondering - will it always feel vulnerable? will I always be at risk of re-injury? If it still feels like this 3 years later, is it time for another look to see if it is getting worse?
