| Re: Thoracic sprain?
I have a herniated disk at T7/8, along with arthritic bone spurs that are pinching nerves and my spinal cord. I CAN tell you it hurts like hell when I use my arms to wash dishes, cook, fold laundry... pretty much using my arms in front of me. I can tell you that a heating pad really help mine to feel better, however I also take pain meds, but they don't do much without the heat. I'm not sure how extensive a dr can go with repairing the T spine. I've heard they can't, or don't want to mess with it.
To answer your question... I'm not sure if you let it go for to long because I really don't know if they can fix it, or want to fix it, unless it is pinching off your spinal cord.
Have you had an mri on it? Try the heating pad and see if that helps. Hope you feel better. I wish I could be of more help to you.
