What Is a Pinched Nerve?


The tissues that surround a nerve such as muscles or tendons may apply pressure to the nerve. When this happens, the nerve’s normal function is disrupted, resulting in a feeling of weakness, tingling, numbness, or pain. This is also known as a pinched nerve. A pinched nerve can occur in various places throughout the body, including the neck and the back.


In the case of the neck/spine, pinched nerves are often caused by degenerative spine conditions. When it first begins, the pain of the pinched nerve may be localized, though it is not unusual to feel sensations in other parts of the body as the pain/sensation will travel through the length of the nerve being affected, causing symptoms such as fingertip numbness or upper body weakness, for example.


Since it’s located in the lower back, the sciatic nerve is especially susceptible to being “pinched” due to too much pressure because spinal degeneration tends to be a common occurrence on the lower back, where the spine has a greater amount of flexibility and must also bear the body’s weight. Herniated discs may occur as well as other conditions that will affect the sciatic nerve, potentially leading to a series of symptoms collectively known as sciatica.
