The spine is a structure which is made of many bones called vertebrae. The spinal cord runs downward through a canal in the center of these bones. Nerve roots leave the cord and course between each vertebra. Any injury or condition that affects the nerve roots is known as radiculopathy, or a pinched nerve.
Studies show that pinched nerves commonly occur in your lower back (lumbar radiculopathy). However, it can also affect your neck (cervical radiculopathy) or other areas of your spine. Tendons and ligaments may compress nerve roots in your spine, and lead to a pinched nerve. When your pinched nerve is caused by a tendon or ligament, it is known as mononeuropathy.
Causes of a Pinched Nerve
The most common cause of a pinched nerve is a herniated disk. There are soft disks located between each vertebrae that act as cushions to offer protection and support. Slipped disk is a condition that occurs when the discs slip out of place or get damaged, and as a result compress your nerves.
Aging is a risk factor for slipped disk. The tendency to develop slipped discs increases as you age. Studies show that over 60% of people older than 50 have herniated discs and pinched nerves without symptoms.
