Pressure on the median nerve – the central nerve that connects to the hand – causes carpal tunnel syndrome. In carpal tunnel patients, it causes pain and lack of function in the hand when squeezed. People whose work requires repetitive hand movements often experience this disorder. For example, people who work on computers and hair stylists commonly experience carpal tunnel syndrome. Pregnant women are also highly susceptible. A wrist splint or exercises can ease symptoms in the early days, however, in advanced cases surgery is necessary.

1. Pins and Needles

Everyone recognizes the tingling sensation known as pins and needles. This easily happens to someone who stays in an awkward position without moving hands and legs over a period. In these cases, the feeling is no more than a slight irritant, but with carpal tunnel syndrome, the sensation is far more intense and unpleasant. Usually, it only affects the thumb and fingers, but it can also spread to other areas.
