Neuropathy refers to damage or dysfunction of the nerves outside the brain and spinal cord (the peripheral nervous system). It often causes numbness, tingling, weakness, or sharp, burning pain, typically starting in the hands and feet. It can be caused by diabetes, vitamin deficiencies, toxins, or infections. (Mayo Clinic)

Symptoms

Symptoms depend on which nerves are damaged. 

• Sensory Nerves: Numbness, tingling ("pins and needles"), burning sensations, and extreme sensitivity to touch.
• Motor Nerves: Muscle weakness, cramping, twitching, and difficulty with balance or coordination.
• Autonomic Nerves: Dizziness upon standing, excessive or lack of sweating, digestive issues, and bladder problems. (Mayo Clinic)
  
  Common Causes
  
  There are over 200 known causes, but the most common include: 
• Diabetes: The leading cause, often resulting from chronically high blood sugar.
• Vitamin Deficiencies: Especially a lack of B vitamins (B-1, B-6, and B-12) and vitamin E.
• Alcohol Misuse: Can lead to poor dietary habits and direct nerve toxicity.
• Autoimmune & Infections: Conditions like lupus, rheumatoid arthritis, Lyme disease, and shingles.
• Medications & Toxins: Certain chemotherapy drugs and exposure to heavy metals. (Mayo Clinic)

Diagnosis and Treatment

Treatments focus on addressing the root cause, slowing disease progression, and managing pain. (Mayo Clinic)

• Diagnosis: Doctors will review your medical history and perform a neurological exam to check reflexes, muscle strength, and sensation. Blood tests and nerve conduction studies may also be used. (Cleveland Clinic)
• Lifestyle & Home Care: Strict blood sugar management for diabetics, daily foot care, regular exercise (like walking or yoga), and limiting alcohol intake. (Mayo Clinic)
• Medications: Pain relievers, anti-seizure medications, and certain antidepressants are frequently prescribed to relieve nerve pain. (Mayo Clinic)
• Therapies: Physical and occupational therapies are highly effective for improving balance, strength, and fine motor skills. (Diane Farber Cancer Clinic)
