Re: Positive cervical MRI, negative EMG/NCS confused...
I would say that your MRI is rather ambiguous as far as needing surgery goes. One thing I would bring to your attention is the "secondary to.... short AP diameter". What he's saying is that your spinal canal is abnormally small from front to back. This is likely caused by short pedicles, which are the bony connections between the vertebrae and the lamina. If you find an illustration of pedicles, you can see that if they are too short, then the spinal canal will be narrow, as will the foraminal openings. This is a condition called "hereditary spinal stenosis", which I also have. The important takeaway here is that having an abnormally narrow canal, and probably also abnormally narrow foramina, means that when things go wrong (or just gradually deteriorate over time), you have less leeway in your canal and/or foramina, and the spinal cord or the spinal nerves will be more readily affected.
In your case, the disk protrusions are pressing into the canal (which is lined by the thecal sac), and your lack of leeway means they are also at least slightly pressing on the spinal cord. What's uncertain is how much effect this will have symptomatically. Spinal cords can be deeply indented or compressed with few or no symptoms, or they can be only slightly compressed with multiple symptoms.
The shock going down into your right middle finger would seem to point to a problem with the C7 nerve, which passes through the C6-7 foramen. That does not necessarily mean the problem is in the foramen (the radiologist does not mention any problem there), as the nerve also could be pinched in the shoulder or elbow.
I'm afraid that, from what I've read, everything is kind of up in the air. I couldn't say for sure that spinal problems are to blame, and I couldn't say that they aren't. I would GUESS that your MRI images look at least a little worse than the radiologist's report makes it seem, or the surgeon would not start out by saying you need surgery.
Still, some of your pain could be due to strained muscles, which can be very painful and also last a long time.
If you can, I'd suggest your get more opinions. You could send your MRI to a different radiologist. You could also see another spinal surgeon or neurologist. That might clarify things.
