What Does Tingling And Numbness In The Neck Indicate?
Cervical spine changes.
Detailed Answer:
I read your question carefully and I understand your concern.
Looking at the description of your symptoms it looks a case of irritation of upper cervical nerve roots which generally occurs in the setting of spinal degenerative changes.
Some degree of degenerative change in the spine is common with age, factors accelerating it in some people may be heavy physical work, neck injuries or simply the influence of genetic factors.
Since it doesn't seem to cause you any real pain and mostly related to position I wouldn't suggest any medication for now, but physical therapy is recommended as the only means of really influencing the degenerative process.
I remain at your disposal for further questions.
