Also called: Neuritis, Peripheral neuritis, Peripheral neuropathy
Your peripheral nerves are the ones outside your brain and spinal cord. Like static on a telephone line, peripheral nerve disorders distort or interrupt the messages between the brain and the rest of the body.
There are more than 100 kinds of peripheral nerve disorders. They can affect one nerve or many nerves. Some are the result of other diseases, like diabetic nerve problems. Others, like Guillain-Barre syndrome, happen after a virus infection. Still others are from nerve compression, like carpal tunnel syndrome or thoracic outlet syndrome. In some cases, like complex regional pain syndrome and brachial plexus injuries, the problem begins after an injury. Some people are born with peripheral nerve disorders.
Symptoms often start gradually, and then get worse. They include
- Burning or tingling
- Muscle weakness
- Sensitivity to touch
Treatment aims to treat any underlying problem, reduce pain and control symptoms.

Hereditary sensory neuropathy type IA is a condition characterized by nerve abnormalities in the legs and feet (peripheral neuropathy). Many people with this condition experience prickling or tingling sensations (paresthesias), numbness, and a reduced ability to feel pain and sense hot and cold. Some affected individuals do not lose sensation, but instead feel shooting pains in their legs and feet. As the disorder progresses, the sensory abnormalities can affect the hands, arms, shoulders, joints, and abdomen. Affected individuals may also experience muscle wasting and weakness as they get older. Weakness in the ankle muscles can make walking difficult. As the condition progresses, some people with hereditary sensory neuropathy type IA require wheelchair assistance.Individuals with hereditary sensory neuropathy type IA typically get open sores (ulcers) on their feet or hands or infections of the soft tissue of the fingertips (whitlows) that are slow to heal. Because affected individuals cannot feel the pain of these sores, they may not seek immediate treatment. Without treatment, the ulcers can become infected and may require amputation of the surrounding area or limb.Some people with hereditary sensory neuropathy type IA develop hearing loss caused by abnormalities of the inner ear (sensorineural hearing loss). Hearing loss typically develops in middle to late adulthood.The signs and symptoms of hereditary sensory neuropathy type IA can begin anytime between adolescence and late adulthood. While the features of this condition tend to worsen over time, affected individuals have a normal life expectancy if signs and symptoms are properly treated.
