Neuropathy means damage to nerves—most often the “peripheral” nerves that live outside the brain and spinal cord and connect the brain to the rest of the body.

What is neuropathy?

Neuropathy (often called peripheral neuropathy) is a group of conditions in which damaged nerves can’t properly send or receive signals. This can affect sensation, movement, or automatic body functions like blood pressure and digestion, depending on which nerves are involved.

In practice, people often notice neuropathy as burning pain, tingling, numbness, or weakness, usually starting in the feet or hands. It can be mild and annoying or severe and disabling.

Key symptoms (quick list)

Common symptoms include:

  • Tingling or “pins and needles”
  • Numbness or reduced ability to feel pain or temperature
  • Burning, stabbing, or electric-shock–like pain
  • Increased sensitivity to touch (even bedsheets can hurt)
  • Muscle weakness, cramping, or loss of coordination
  • Balance problems, falls, or unsteady walking
  • Changes in blood pressure, heart rate, sweating, or digestion (with autonomic neuropathy)

Main types of neuropathy

Doctors often divide neuropathy into types based on which nerves are affected:

  • Sensory neuropathy – affects feeling (pain, temperature, vibration, touch); often causes numbness, tingling, or burning pain in feet and hands.
  • Motor neuropathy – affects movement; can cause muscle weakness, twitching, or difficulty with tasks like walking or speaking.
  • Autonomic neuropathy – affects automatic functions; can cause dizziness when standing, abnormal sweating, gut or bladder problems, or sexual dysfunction.
  • Focal/mononeuropathy vs. polyneuropathy – one nerve only (like carpal tunnel) vs. many nerves, often starting symmetrically in both feet.

Common causes

There are many causes; sometimes no clear cause is found.

  • Diabetes (one of the most common causes worldwide)
  • Alcohol misuse
  • Vitamin deficiencies (especially B vitamins)
  • Certain medications (including some chemotherapy drugs)
  • Infections (for example, shingles)
  • Autoimmune diseases and inflammatory conditions
  • Kidney disease, liver disease, thyroid problems
  • Physical injury or nerve compression (e.g., herniated disc, entrapment)
  • Genetic (inherited) neuropathies

Is neuropathy curable or treatable?

Neuropathy can be temporary and reversible if the cause is found and treated early, but it can also be long‑term or permanent. Even when nerves don’t fully recover, many people can reduce symptoms and improve function with:

  • Treating the underlying cause (for example, better blood sugar control in diabetes)
  • Medications for nerve pain
  • Physical therapy and balance training
  • Lifestyle changes (exercise, limiting alcohol, foot care, etc.)

Quick safety note

If someone suddenly develops severe weakness, rapidly spreading numbness, difficulty walking, problems with bladder/bowel control, chest pain, or trouble breathing, they should seek emergency care. These can signal serious nerve or spinal problems that need urgent attention.
