#Carpaltunnel is a narrow passageway surrounded by #bones and #ligaments on the palm side of your hand. It is caused by pressure on the #mediannerve. The anatomy of your #wrist, health problems and possibly repetitive hand motions can contribute to #carpaltunnelsyndrome. When the median nerve is compressed, the symptoms can include #numbness, #tingling and #weakness in the #hand and #arm.
Symptoms usually start gradually and include:
1. Tingling or numbness in your fingers or hand. Usually the thumb and index, middle or ring fingers are affected. You might feel a sensation like an electric shock in these fingers. The sensation may travel from your wrist up your arm. These symptoms often occur while holding a steering wheel, phone or newspaper, or may wake you from sleep.
2. Weakness. You may experience weakness in your hand and drop objects due to the numbness in your hand or weakness of the thumb's pinching muscles, which are also controlled by the median nerve
3. Workplace factors. Working with vibrating tools or on an assembly line that requires prolonged or repetitive flexing of the wrist may create harmful pressure on the median nerve or worsen existing nerve damage, especially if the work is done in a cold environment.
