Carpal tunnel syndrome is a common nerve condition that occurs when the median nerve in the wrist becomes compressed, leading to numbness, tingling, weakness, or pain in the hand and fingers.

Quick Facts

  • Affects the median nerve, which controls sensation and movement in parts of the hand
  • Often develops gradually and may worsen without treatment
  • Common in people who perform repetitive hand or wrist motions
  • Can affect one or both hands
  • Early treatment can help prevent permanent nerve damage

Symptoms of Carpal Tunnel Syndrome

Carpal tunnel symptoms typically start slowly and may include:

  • Numbness or tingling in the thumb, index, middle, or ring finger
  • Hand or wrist pain, especially at night
  • Weakness or clumsiness when gripping objects
  • Dropping items unexpectedly
  • A burning or aching sensation that may travel up the arm

What Causes Carpal Tunnel Syndrome?

Carpal tunnel syndrome occurs when pressure builds within the carpal tunnel, a narrow passageway in the wrist that protects the median nerve and tendons. Common causes include:

  • Repetitive hand or wrist movements
  • Prolonged wrist flexion or extension
  • Swelling or inflammation in the wrist
  • Wrist injuries or fractures
  • Underlying health conditions affecting nerves or joints

Symptoms of Carpal Tunnel Syndrome

People at higher risk for carpal tunnel syndrome include those who:

  • Perform repetitive or forceful hand motions
  • Use vibrating tools or keyboards frequently
  • Have diabetes, arthritis, or thyroid disorders
  • Are pregnant or experience fluid retention
  • Have a family history of nerve compression conditions

Treatment Options for Carpal Tunnel Syndrome

  • Treatment depends on symptom severity and underlying cause, and may include:
    • Wrist splinting, especially at night
    • Activity modification or ergonomic adjustments
    • Anti-inflammatory medications
    • Physical or occupational therapy
    • Corticosteroid injections
    • Minimally invasive or surgical release of the carpal tunnel in severe cases
