The cervical spine is capable of producing paresthesias (pins and needles or tingling) depending upon the structures affected. Normally, nerve compression will cause arm tingling (and normally only on one side). This tingling becomes worse with neck extension (bending the neck backwards) and becomes better with neck flexion (bending forward).
The neck is not capable of causing jaw pain or tingling in the face. Those nerves are cranial nerves and do not exit out from the head.
Leg tingling can occasionally be caused by the neck but this is unusual and is related to other symptoms of myelopathy (compression of the spinal cord). See the website for description of these symptoms.
