Well, lets see:

At C5-6 you have a disc bulge with overgrowth of bone and narrowing of the hole that the nerves pass thru going to the spinal cord.

At C3-4 and C4-5 it's the same as above.

At T1-2 you have a disc bulge with no spinal cord impingement. (the thoracic level is the level between your cervical spine and the lumbar spine.)

Fusion at C6-7 -- everything is great.

This really doesn't show what could be cause any extreme pain -- or much of any pain at all.

Have you seen a Neurologist/Neurosurgeon?? Perhaps he could give you a better idea of what you might be suffering from. That's who I would take my films to next. I hope you can find some reason for your pain. I wish you the very best. God bless and take care. Hugs, Lee
