Median nerve compression in the wrist or Carpal Tunnel Syndrome (CTS) is caused by the thickening of the carpal tunnel, a narrow tube located on the palm-side of your wrist, from repetitive hand motions or positioning your hands at the same angle for a long period of time. The inflammation of the carpal tunnel then compresses the median nerve as it passes into your hand. The median nerve provides sensation to the thumb, index finger, long finger and half of the ring finger. The impulse to the muscle that leads to thumb is also supplied by the median nerve.

When the median nerve is being compressed by excess pressure in the carpal tunnel, it causes you to feel numbness, weakness, pain and burning sensation on your hand and on the side of your fingers. You can also experience pain that feels like an electric shock in your hand in the middle of the night or after waking up in the morning or after a continuous use of your hand. You will experience constant pain when the symptoms become severe. Carpal Tunnel Syndrome (CTS) will affect the impulse of your muscles and reduce the strength of your grip and leads to difficulties in carrying objects or frequently dropping them.

 “Actually, the function of fascia in the carpal tunnel is to increase the strength of your wrist and hold the weight/force of the hand as well as helping the tendons in the tunnel to work effectively. However, due to the excess use of your hand in a tight grip for a long time, an inflammation of the carpal tunnel occurs. The tube can swell up to 3-4 millimeters to the point that it compresses the median nerve. The Carpal Tunnel Syndrome (CTS) is commonly found in people who use their hands in bent position for an extended period of time and frequently employ vibrated tools.” Said Dr. Nararit Luanchumrorn, a physical medicine and rehabilitation doctor.  For further information and booking an appointment, kindly contact  Advanced Rehabilitation Center, 5th – 6th floor, Vejthani Hospital, or call +66(0)85-223-8888 (English Hotline).
