listening from your problems This seems to me as a case of cervical spondylosis
with right sided compressive radiculopathy
at C5,C6,C7 levels . I think you must go for further investigations like MRI
and NCVT and blood tests. Clinically looks you may need surgery . but final opinion is to be made after investigations like MRI.
Any how if you are suppose to under go for operation I think you will not problems. Routinely these operations are being performed by ortho and spinal surgeons.
Regarding risk of anaesthesia it is not ,Untill you hav a major other problem which may create a problem in anaesthesia. Age is no Bar.
pl first evaluate your investigations
