4 Signs You May Have Nerve Damage

Introduction

• Nerve damage can occur from injuries such as:
  • Trauma from car accidents leading to crushed or torn nerves (avulsion)
  • Deep cuts from knives or machines damaging nerves
• Symptoms of nerve damage can vary.

Signs of Nerve Damage

1. Numbness

   • Numbness in skin areas near the injury site.

2. Weakness

   • Feeling of weakness near the injury site.

3. Motor Function Impairment

   • Inability to perform certain movements.

4. Pain

   • Pain at the injury site or along the nerve.

Understanding Nerve Damage

• Nerves function as the body's communication system:
  • Send messages to the brain for movement
  • Signal when experiencing pain, pressure, or temperature extremes
• Damage disrupts message transmission leading to symptoms like numbness or movement issues.

Treatment Options

• Initial Steps

  • Assessment by a hand surgeon and neurologist
  • Diagnostic tests include EMG (Electromyography) and NCS (Nerve Conduction Study)

• Surgical Intervention

  • Nerve repair surgery involves stitching the nerve or using a nerve graft
  • Graft used to bridge cut nerve ends
  • Nerve regeneration is slow: approximately one inch per month
  • Severe injuries may take months to heal and full function may not be regained.

Action Steps

• Contact a hand surgeon promptly if nerve damage is suspected.
