Symptoms

Symptoms of neuropathy vary depending on the type and location of nerves affected:
Sensory symptoms:

• Numbness or reduced ability to feel pain or temperature
• Tingling or burning sensation
• Sharp, stabbing, or electric-shock-like pain
• Extreme sensitivity to touch

Motor symptoms:

• Muscle weakness
• Loss of coordination or balance
• Muscle cramps or twitching

Autonomic symptoms:

•  Dizziness or fainting due to blood pressure fluctuations
• Digestive issues (nausea, constipation, diarrhea)
• Bladder or bowel dysfunction
• Sexual dysfunction
• Abnormal sweating

Diagnosis

A thorough evaluation is required to diagnose neuropathy and its cause:
Medical history and physical examination
Neurological tests:

• Reflexes, muscle strength, coordination, and sensory function

Electrodiagnostic tests:

• Nerve conduction studies (NCS)
• Electromyography (EMG)

Blood tests:

• To identify diabetes, vitamin deficiencies, infections, or autoimmune diseases

Imaging:

• MRI or CT scans to rule out structural causes

Nerve biopsy or skin biopsy:

• Occasionally used to examine nerve damage

Conventional Treatment

The treatment of neuropathy focuses on managing symptoms and treating the underlying cause:
Medications:

• Pain relievers: NSAIDs for mild cases; opioids for severe pain (short-term use)
• Anti-seizure drugs: Gabapentin, pregabalin to reduce nerve pain
• Antidepressants: Amitriptyline, duloxetine for pain relief
• Topical treatments: Capsaicin cream, lidocaine patches

Treatment of underlying condition:

• Blood sugar control in diabetic neuropathy
• Vitamin supplementation
• Immunosuppressants for autoimmune neuropathies
• Antiviral or antibiotic therapy for infections

Physical therapy:

• Strengthening and stretching exercises
• Balance training to reduce fall risk

Occupational therapy:

• Adaptations to improve daily function and independence

Orthotic devices and assistive tools:

• Braces, special shoes, or mobility aids for walking support

Regenerative and Emerging Therapies

Stem Cell Therapy:

• Overview: Use of mesenchymal stem cells (MSCs) to promote nerve repair and reduce inflammation

Mechanism:

• Secrete neurotrophic factors
• Modulate immune response
• Promote angiogenesis and regeneration of damaged nerves

Applications:

• Diabetic neuropathy
• Chemotherapy-induced neuropathy
• Autoimmune neuropathies

Platelet-Rich Plasma (PRP):

• Injected near nerves to stimulate regeneration
• Under investigation in peripheral nerve injury treatment

Hyperbaric Oxygen Therapy (HBOT):

• Mechanism:
  • Increases oxygen supply to nerve tissue
  • Reduces oxidative stress and inflammation
  • Promotes neovascularization
• Applications:
  • Diabetic foot ulcers with neuropathy
  • Peripheral neuropathy due to radiation or toxins
• Evidence: Research show reduced pain and improved function

Lifestyle and Supportive Management

• Healthy diet: Rich in fruits, vegetables, whole grains, and lean proteins
• Blood sugar control: Especially important in diabetic neuropathy
• Alcohol reduction or cessation
• Regular exercise: Improves blood flow and nerve health
• Foot care: Regular inspection, proper footwear, and hygiene to prevent injuries and infections

Psychological Support

Chronic neuropathic pain can lead to anxiety, depression, and sleep disorders. Psychological interventions include:

• Cognitive-behavioral therapy (CBT)
•  Mindfulness and relaxation training
• Support groups and counseling

Prognosis

Prognosis depends on the cause and timeliness of intervention. In many cases, symptoms can be managed, and progression slowed. Early treatment of reversible causes, such as vitamin deficiencies or diabetes, can result in partial or full recovery. In chronic or inherited cases, symptom control and rehabilitation remain the primary goals.
