Carpal Tunnel Syndrome

Bundles of fibers are known as Nerves which form a system that passes information to the brain, spinal cord, and body organs. Muscles are controlled by the nerves which provide senses to the body. Any nerve failure will have an adverse effect on the body.

The nerve which travels through the wrist is called median nerve. Several nerve roots constituently forms median nerve which emerges from lower neck. The median nerve creates a link from brain and spinal cord to the finger tips. It provides the sensual information to the muscles of the hand, to the palm, thumb, index finger, the middle finger and the ring finger. Finger movement is also regulated by the median nerve which contains a bundle of ligaments.

When the median nerve got pinched, it causes pain and numbness in the hand which is known as Carpal Tunnel Syndrome. Starting from lower neck, the median nerve travels between arm to the wrist and hand. In this path the nerve can be captured anywhere. When the compression on median nerve is formed in the carpal tunnel, it doesn’t allow the nerve to function correctly. A bone on one side and an unbending ligament on the other side surround the carpal tunnel; and the nerve doesn’t find any place to move. So, the nerve gets squished.

Carpal is a Geek word which stands for ‘wrist’, which provides the tunnel its name. Wrist bones are gasped by tight ligament which makes the carpal tunnel.

Symptoms of Carpal Tunnel Syndrome

The symptoms persists commonly in people aged 40-60, particularly women. The identifiable pinched nerve symptoms of Carpal Tunnel Syndrome:

  • Painful tingling in hands
  • Weakness in fingers
  • Feeling of swelling in fingers without no apparent swelling
  • Shooting pain through arm

Causes of Carpal Tunnel Syndrome

  • Arthritis
  • Inflammatory Musculoskeletal Conditions
  • Fractures, dislocations and abnormal bone growth puts pressure on median nerve.
  • New growth like tumors and cysts in the wrist and carpal area.
  • Repetitive movement of hands and wrists.
  • Activities like driving, repetitive keyboard typing can also cause carpal tunnel syndrome.
  • Aging can also lead to carpal tunnel syndrome as the bones and ligaments grows old with the person.
  • Smoking impairs blood flow to the median nerve.
