Causes of Carpal Tunnel Syndrome

Anything that causes irritation, swelling, fluid buildup, or a growth in or around the carpal tunnel can cause this syndrome. Common causes are:
  • Repetitive movements of the hands, wrists, or fingers, such as with a computer keyboard, certain musical instruments, or hand tools
  • Use of vibrating tools
  • Wrist fracture or dislocation
  • A narrow carpal tunnel (due to heredity or other causes)
  • Arthritis swelling
  • Diabetes
  • Water buildup from:
  • Hormone-related conditions, such as pregnancy or thyroid problems
  • Tumors and cysts in the carpal tunnel
