Age, injury and genetics can cause a bulging disc in the neck according to the Laser Spine Institute. A bulging disc occurs when cartilage between between bones bulge outward.
As a person ages, the higher risk they have of incurring a bulging disc. This is due to the cartilage weakening. Injuries that put an abnormal amount of stress on the body can also cause a bulging disc. People with a family history of the condition are also at greater risk. A bulging disc in the neck can be painful. There are different treatments available to lessen the symptoms. Only a doctor can diagnose the condition.
