The symptoms you have given need to be examined on your body, or you can a Physical examination is required. The symptoms are suggestive of Cervical Spndylosis, it is a condition where there is stiffness
at back of neck, an abnormal sensation running from back of neck to head or shoulders or hands or down the back.
I would suggest you see a good Orthopedic surgeon and Physiotherapist for a rationla treatment.
In addition to this i would suggest you to decrease your stress
level also because that also at times is the cause.
You can also consult Homoeopathy, it is also quiet effective.
Wish you a speedy recovery to health.
