Nerve entrapments or impingements involving the median, radial, and ulnar nerves in the hand can lead to wrist pain and impair hand function.
Median Nerve Entrapment / Impingement
The median nerve is a major nerve in the forearm and hand that supplies sensation to the thumb, middle finger, index finger, and half of the ring finger. Compression or entrapment of the median nerve can happen due to carpal tunnel syndrome, compression of muscle in your forearm, and repetitive flexion.
Radial Nerve Entrapment / Impingement
The radial nerve, which runs down the back of your arm, controls movement and sensation in the back of the hand, thumb, and fingers. Compression or entrapment of the radial nerve can happen due to prolonged pressure on the arm, sleeping in an awkward position, fracture, or trauma.
Ulnar Nerve Entrapment / Impingement
The ulnar nerve, which runs from the neck down to the arm, can become entrapped or compressed due to repetitive elbow bending or pressure on the wrist.
