![]() How Can You Get Compensated for Peripheral Nerve Damage? A herniated disc in your neck could disrupt your shoulders and arms, while a herniated disc in your lower back could affect your hips and legs. Nerve injuries often cause symptoms to radiate to areas below the immediate site of the injury. Loss of vision, hearing, smell, or taste.Loss of sensitivity to temperature or pressure.Your senses collect information about the world so your brain can control your body.ĭamage to the nerves carrying signals from your sensory organs to your brain can cause: ![]() Thus, you might suffer paralysis and drooping facial features from a damaged cranial nerve even though a traumatic injury did not harm your face. Since these symptoms result from nerve damage, the symptoms might appear in an uninjured body part. If something disrupts the autonomic nerves, you might have difficulty controlling your bowel or bladder. Your waste system also uses a combination of autonomic and motor signals. The brain uses autonomic signals to control your body’s involuntary processes.Īn injury to autonomic nerves can produce symptoms like: Peripheral nerve damage can cause many symptoms depending on the type of nerve signal disrupted. What Are Some Symptoms of Peripheral Nerve Damage? The inflamed nerve can then misfire or drop signals. When something presses on a nerve, the nerve gets irritated and inflamed. A dislocated or fractured bone can press on nearby nerves as well. Swelling from an injured hip can pinch nerves that run to the feet and toes. This often happens when nearby tissues get injured.Ī herniated disc can press on the nerve roots that branch from the spinal cord. CompressionĪ compressed nerve, also called a pinched nerve, is one of the most common forms of nerve damage. If administered incorrectly, these anesthetics can permanently close those channels. Some local anesthetics, for example, work by blocking the channel that neurons use to move charged particles to their surfaces. As a result, the nerve endings will not detect sensations. BurnsĪ chemical, thermal, or radiation burn can destroy nerve endings in the skin. ![]() The nerves in the infant’s brachial plexus get stretched, causing nerve damage that can affect the baby’s entire arm. A stretched nerve can occur when a body part gets hyperextended due to an accident, assault, or medical malpractice.įor example, Erb’s palsy happens when a doctor pulls too hard on a baby’s arm during birth. A laceration can happen in any accident, from a car crash to a workplace accident. This injury is analogous to cutting an electrical wire. Traumatic nerve damage can result from many types of injuries, including: LacerationsĪ laceration, particularly a deep skin tear, can sever nerves, leaving the nerve signals unable to jump the gap. If they get stretched, a nerve signal might weaken as it travels down the nerve, or the nerves might send errant nerve signals. When nerves get severed, they cannot carry nerve signals. This changes the neuron’s charge, causing the next neuron to change its charge, and so on down the nerve. When a nerve detects a change in the electrical charge of an adjacent neuron, it moves charged particles to its surface through a channel in the cell. Nerves are made of neurons, which carry and pass nerve signals to each other using a combination of chemical and electrical signals. Doctors also use the phrase “neuropathy” to refer to peripheral nerve damage. The term “nerve damage” usually refers to damage to the peripheral nervous system rather than the CNS. It contains everything outside of the CNS, including: This makes the phrase “peripheral nervous system” somewhat confusing because the peripheral nervous system includes more than just the peripheral nerves. Thus, a nerve root that diverges to the left from the spinal cord in your lower back controls your left hip, leg, foot, and toes. The spinal cord is part of the CNS, but the nerves that branch off from the spinal cord - known as nerve roots - are part of the peripheral nervous system.Įach nerve root carries nerve signals to and from a region of the body, further branching into peripheral nerves that connect to individual muscles, organs, and nerve endings in the skin. The spinal cord runs between your brain and your body. They also carry motor signals to the muscles in your face and neck. These nerves carry sensory perceptions to your brain from your eyes, tongue, ears, nose, and facial nerve endings. The peripheral nervous system connects the central nervous system to the entire body and splits among two sets of nerves.Ĭranial nerves run between your brain and throughout your head. ![]() The central nervous system (CNS) includes your brain and spinal cord, handling the control and most of the communication of your nervous system. Doctors divide the body’s nervous system into two parts. ![]()
