What kinda exercises are good for numbness in hand due to hnp in my cervical spine? my fingers become most numb usually after i wake up

Before discussing: Specific treatment or exercises for the neck or cervical spine you should be evaluated for a carpal tunnel syndrome as that is a very common condition that can lead to this pattern of symptoms or you may be " doubly" affected by a "pinched " nerve in your neck as well as at the wrist which is known as a " double crush syndrome"! so see your doctor first to get a correct diagnosis.
