Stenosis just means that the internal diameter of the spinal canal is narrower than "normal". Spurring, depending upon where it is located, can be a cause of the narrowing. Unless, this narrowing is significant enough to put pressure on the nerve roots, or the cord itself, it does not mean anything other than a finding on the MRI (or CT).
If you have pressure on the C6 and C7 nerve roots, causing a radiculopathy, it may mimic the symptoms of carpal tunnel syndrome. That is usually one thing that is differentiated by having electrical studies done. Also, both can occur at the same time, then it is called a "double crush" syndrome.
So, unless the spurring and stenosis is putting pressure on the nerve roots, it wouldn't cause the symptoms in the hand.
But, if you are concerned about the findings, discuss it again with your physician.
