Some nerves only transmit sensation, so a nerve injury to these nerves would cause some amount of numbness. In addition to sensory nerves, some nerves give you the ability to move, and other nerves do both of these things.
Injury to nerves that carry motor signals causes some amount of weakness. This is frequently a symptom after nerve injury. The pain present after a nerve injury can be anywhere along the course of the nerve, but it is typically at the injury site. Mild injuries to the nerve: The nerve can repair itself, either within minutes or after a number of weeks. During this time, messages between the brain and body can be altered.
Supportive treatment often helps, but in some cases surgery is needed. Broken nerve fibers or more severe injuries: The nerves can grow back to their muscle or skin areas, but this process can take several months, and the messages between the brain and body will stop until the nerves grow.
Treatment may be supportive care, but surgery may be needed depending on the type of injury. Cleveland Clinic is a non-profit academic medical center. Advertising on our site helps support our mission. We do not endorse non-Cleveland Clinic products or services.
Neuropathy Neuropathy — also called peripheral neuropathy — refers to any condition that affects the normal activity of the nerves of the peripheral nervous system. Causes can be both inherited and acquired. Diabetes is often a factor. Sensory nerves carry messages from your senses through your spinal cord to your brain. For example, they tell your brain you are touching something hot. Motor nerves travel in the opposite direction. They carry messages from the brain to your muscles. They tell your muscles to move you away from the hot surface.
Autonomic nerves are responsible for controlling body functions that occur outside our control, such as breathing, digestion, heart rate, and blood pressure. How common is neuropathy? Hereditary neuropathy The most common hereditary neuropathy is Charcot-Marie-Tooth CMT disease , which affects both motor and sensory nerves. Acquired neuropathy Acquired neuropathy is much more common.
There are many causes of acquired neuropathy, including: This includes sudden injury from an event such as a fall, car accident or sports activity. Trauma to the peripheral nerves can also occur from compression of the nerves due to repetitive stress or narrowing of the nerve space.
Infections and autoimmune disorders: Among the germs that can damage nerve fibers are human immunodeficiency virus HIV , the herpes virus , and the bacteria that cause Lyme disease and syphilis. Some autoimmune disorders can also affect nerve tissue. Systemic diseases are those that affect the entire body. These include diabetes — the leading cause of peripheral neuropathy — kidney disorders, certain cancers, and hormonal imbalances. Some medicines, including the strong medicines used to treat cancer chemotherapy , can damage peripheral nerves.
Exposure to toxic substances such as heavy metals including lead and mercury and industrial chemicals, especially solvents, can also affect nerve function. Neuropathy can occur when blood flow to the arms and legs is hindered by inflammation, blood clots, or other blood vessel disorders. Decreased blood flow deprives the nerve cells of oxygen, causing nerve damage or nerve cell death.
Excessive use of alcohol can rob the body of thiamine and other essential nutrients, leading to neuropathy in the arms and legs. What are the symptoms of neuropathy? Common symptoms of sensory neuropathy include: Numbness, especially in the hands and feet. Changes in sensation — Some people feel severe pain, especially at night, and some are unable to feel pain, pressure, temperature, or touch.
Nerves injuries can be caused by pressure, stretching, or cutting of the nerve. If your nerve is injured, you may feel numbness, weakness or pain in the injured. In carpal tunnel syndrome, pressure on the median nerve in the wrist causes damage. Or the nerves may be crushed, cut or damaged in an. The most severe type of nerve injury is an avulsion (A), where the nerve roots Less severe injuries involve a stretching (B) of the nerve fibers or a rupture (C).
