Cause

The median nerve and several tendons from your forearm travel through a small space in your wrist called the carpal tunnel. Often, when the wrist is in a flexed position repetitively, the median nerve can become compressed underneath the tendons in the carpal tunnel. This can cause numbness, pain and weakness in the hand. You should be aware of dangerous movements that can increase the stress on the carpal tunnel and eventually lead to pain and injury. These movements include slopers, underclings and sidepulls. All these movements flex the wrist into extreme positions and can increase the pressure in the carpal tunnel.
