According to Medline Plus, pain in the right side of the neck can be caused by a variety of factors that include poor posture, injuries and medical conditions such as arthritis. While certain types of neck pain are not considered dangerous, it is important to consult with a physician if neck pain is the direct result of an accident or is accompanied by numbness, swollen glands or breathing difficulties.

The Mayo Clinic explains that neck pain can also be caused by fibromyalgia, a chronic condition that causes pain throughout the body. Fibromyalgia symptoms may be triggered by stress, physical injury or illness. In certain cases, symptoms develop without an underlying cause. Additional symptoms can include fatigue, headaches and concentration difficulties.

WebMD explains that pain on either side of the neck may indicate cervical spinal stenosis, a condition in which the spinal canal becomes narrowed. In addition to neck pain, symptoms can include pain in the back and shoulders, weakness in the neck, loss of balance due to spinal cord damage and incontinence. The condition often occurs in individuals aged 50 or older. As people age, natural changes in the size and shape of the spinal canal are common. These changes can lead to bulging discs, which in turn can lead to pain throughout the neck and spine.
