Nerve damage can cause chronic pain, numbness, weakness, and long-term disability. Learn how nerve injuries happen, what symptoms to watch for, and how compensation may be available.
Causes of Nerve Damage
Doctors usually use the term “nerve damage” to identify an injury in the peripheral nervous system. If you damage your central nervous system, doctors will identify the injury as a brain injury or a spinal cord injury. Peripheral nerve damage can happen in a few ways, including when a nerve gets:
- Severed: Nerves carry signals using a combination of electricity and chemistry. When a nerve cell gets stimulated, it passes charged atoms, called ions, to its surface. The next nerve cell detects the electric charge and passes its ions to the surface. This chain reaction continues to pass a nerve signal along the length of the nerve. When a nerve gets severed, nerve cells cannot pass signals to each other across the gap created. A laceration can sever a nerve. For example, if you suffer a deep cut in your leg in a car accident, you might have symptoms of peripheral nerve damage in your foot afterward. A broken bone can also sever a nerve. In a displaced fracture, the broken ends of the bone move out of alignment after the break. As the broken bone displaces, it can tear nerves.
- Burned: Burns are chemical reactions that destroy tissue. Whether a burn results from heat, combustion, caustic chemicals, or radiation, a burned nerve cannot carry a nerve signal.
- Stretched: Traction forces on a nerve can stretch it. As the nerve stretches, the cells get damaged. Signals lose strength or get completely lost as they travel the damaged nerve.
- Compressed: A compressed nerve, also called a pinched nerve, happens when swelling or a dislocation presses on a nerve. For example, a herniated disc in your spine can press on a nerve root after a slip and fall accident.
