Carpal Tunnel Syndrome is a painful condition that affects your hand. This happens when the nerve (median nerve) within your wrist gets compressed.
The fiber that connects the brain and spinal cord with various parts of the body (aka receptor organs) is called a nerve. Nerves transmit impulses from the brain/spinal cord to the receptor organs and they also transmit impulses from the receptor organs back to the brain/spinal cord.
A network of nerves, called the brachial plexus, branches from the spinal nerve and supplies the arm and parts of the shoulder. One of the main nerves branching from the brachial plexus is the median nerve.
The anterior interosseous nerve of forearm, common palmar digital nerves, and muscular and palmar branches, and a communicating branch with the ulnar nerve compose the branches of the median nerve. When the median nerve gets compressed as it passes through the canal within the wrist, carpal tunnel pain occurs.
The median nerve and nine flexor tendons pass through the carpal tunnel or canal which is a tiny passageway. Compression of the median nerve can happen when any one of the flexor tendons gets inflamed which results in the narrowing of the canal.
The distribution of the median nerve is into the skin on front of lateral part of the hand, most of flexor muscles of front of forearm, most of short muscles of thumb and elbow, joint, and many joints of hand. General sensory is its modality.
What happens when a median nerve gets compressed within the wrist like in the case of Carpal Tunnel Syndrome? When this nerve gets compressed by any factor, there is an interruption of the transmission of impulses from the sensory nerve fibers.
This interruption results in a total or partial lack of sensation in the hand. Tingling is often present with the numbness.
The intense numbness is the reason why the afflicted person often wakes up at night. The ‘carpal tunnel pain’ is actually this intense numbness.
The reason why the median nerve gets compressed during sleep at night is because people tend to sleep with their wrist bent. The use of the wrist brace is beneficial especially at this time.
If you experience a constant numbness and tingling in your hand, you may be suffering from Carpal Tunnel Syndrome. Consult your doctor straightaway.
