Cervicalgia is neck pain that occurs toward the rear or the side of the cervical (upper) spinal vertebrae. It generally is felt as discomfort or a sharp pain in the neck, upper back, or shoulder. The term cervicalgia covers a broad range of neck pain causes, including whiplash, muscle strain, ligament sprain, and inflammation of the neck joints. It also can be caused by a number of issues in the region of the cervical vertebrae, including a bulging disc, a pinched nerve, narrowing of the spinal canal (stenosis), spinal arthritis, or degenerative disc disease.
Symptoms of cervicalgia include: sharp or constant pain in the neck, pain associated with rotating or twisting the head, tightness or stiffness in the neck, shoulders or upper back, tenderness when the area is touched, headaches.
