Ankylosing spondylitis (AS) can cause spine pain but no arm or leg pain so we can rule that out as a cause of your “tingling and numbness down my right arm into my hand and fingers as well as electrical shooting pains down my right shoulder blade”. The cervical spine can degenerate regardless of the presence of AS and that appears to be the source of your symptoms.
Carpel tunnel syndrome (CTS) can cause tingling and numbness (paresthesias) from the wrist into the hand and even up the arm somewhat. CTS does not cause shoulder symptoms. See the section on CTS here on the website to understand this disorder more completely.
The C6 nerve exits between C5-6 and C7 exits between C6 and 7. Check the section “symptoms of cervical nerve injuries” to understand what type of symptoms each nerve can generate.
“Moderate bilateral neural foraminal stenosis” at C5-6 and C6-7 more likely can be the source of your symptoms. An increase of the paresthesias in your arm with neck extension would be the typical findings with the origin from your neck.
