What Is a Pinched Nerve?

The term pinched nerve refers to a condition in which a nerve is pressed by its surrounding tissues (bones, cartilage, muscles, etc.) and its normal function has been disrupted because of the pressure. Pain, numbness or tingling, and a pins and needles type sensation are common signs that would suggest the possibility of a pinched nerve.

Where Does a Pinched Nerve Develop?

Nerve compression can occur in many locations throughout your body. Typical sites include your lower spine (lumbar region) and neck (cervical region).

A pinched nerve in the back often results in sciatica, or pain that radiates down to the back of your legs. A pinched nerve in the neck or back may cause radiating pain, numbness, tingling, and weakness. ​Nerve compression is not restrained to spinal nerve roots alone. For example, a pinched nerve in your wrist can lead to carpal tunnel syndrome, pain and numbness in your hand and fingers.​

There is generally no need to be concerned about a pinched nerve that is compressed for a short period of time. Once the pressure is relieved, normal nerve functions are restored. However, pinched nerves that are not released in a timely manner can lead to much more serious issues such as chronic pain, nerve death, or muscle atrophy.
