At T9-10 you have a disc bulge. There is also annular tear in that area. The annula is the fluid filled sac that the disc sits in.

It would be hard to say if this was the result of shoveling snow. These can be from general wear & tear.

If you're having a lot of pain, your best bet would be physical therapy. Ask your doc for a referral to PT -- also ice helps the pain too. Heat generally makes the pain worse as it draws blood to the heated area and causes more swelling & pain. Ice reduces the swelling & relieves the pain. Make sure you wrap the ice in a towel, so it's not directly on the skin!

Best of luck! I hope your pain is reduced soon. God bless. Hugs, Lee
