my age 44 everyday i use motor bike for 40 km since 1 month i have been suffering num ness in my hand while sleeping today i foud though xray that in c5&6 having narrow gap so please consult about what kind of precution to be  YYYY@YYYY
Yes most certainly. A narrowing of the gap presses on the nerve roots which arise from the spine. C5 and C6 are involved in the formation of what is called the brachial plexus which is essentially the neural center of our entire hand. Hence, compression of those nerve roots can lead to numbness and even tingling sensations in the hand recommend you show it to an orthopedic as soon as possible. In the meantime
