The symptoms you reported (neck pain and stiffness, tremor in right hand, tingles in head and face) might be related to cervical spondylosis. Spondylosis is a degenerative arthritis of the joints between the vertebrae. When the cervical vertebrae are affected, it is called cervical spondylosis.


The symptoms that are found in spondylosis are due to the pressure that is put on the nerves leaving the spinal cord and the lack of blood flow. The symptoms might include pain along the nerves, tingling or burning sensation, tremor in the extremities, and even disturbances in balance.


The conservative treatment uses nonsteroidal anti-inflammatory drugs (NSAID). Learning to change the position of the head and the posture, which might change the pressure on the nerves, might turn out to be extremely helpful. Avoid sitting in one position with a stiffened neck for too long.
If the condition is too severe then surgery might be recommended by an orthopedist or neurosurgeon whom you are advised to visit.
