Why this topic matters
Peripheral neuropathy is an umbrella term for conditions involving damage to the peripheral nervous system. Symptoms such as burning, tingling, numbness or weakness can sound similar across conditions, so educational context is useful—but it is not a diagnosis.
Not one single condition
NINDS notes that more than 100 types of peripheral neuropathy have been identified. They can affect sensory, motor and autonomic nerves in different combinations.
Common symptoms
Sensory neuropathy can involve pain, tingling, reduced vibration or touch sensation and difficulty sensing temperature. Motor involvement can cause weakness, cramps or muscle changes.
Common causes
Possible causes include diabetes, injuries, autoimmune conditions, kidney or liver disease, vitamin imbalances, alcohol, toxins, infections and certain medications.
Evaluation and treatment
Treatment depends on the cause and type of nerve damage. Medical history, neurological examination and laboratory testing may be used to identify contributing conditions.
When to seek professional advice
Seek urgent care for sudden one-sided weakness, facial droop, severe new headache, major loss of coordination, or other acute neurological changes. For persistent symptoms, a clinician can help identify the cause and appropriate testing.
