The pain at the back of the neck must be checked at a regular hospital immediately to determine whether the local tingling symptoms are caused by cervical spondylosis or cervical disc herniation, especially in patients with cervical spondylosis, who are particularly prone to the painful sensation of pins and needles on the back side of the neck. When degenerative lesions of cartilage occur in the cervical intervertebral disc for various reasons, local calcification will gradually appear and evolve into local osteophytes. Once the osteophytes neither compress the nerves and blood vessels of the cervical spine nor compress the spinal cord, but only squeeze and stimulate the surrounding soft tissues or other structures, it will be similar to stabbing into the body like a needle, which will easily cause local pins and needles-like pain.
