Carpal tunnel syndrome, which is caused by a pinched nerve in the wrist, is a hand and arm condition that causes numbness, tingling and weakness. Symptoms usually present gradually with numbness or tingling in the thumb, index, and middle fingers.
In general, anything that compresses or irritates the median nerve can lead to carpal tunnel syndrome. Inflammatory conditions, which narrow the tunnel that protects the nerve, your general wrist and hand anatomy, as well as repetitive motion activities, are all contributing factors.
After a physical examination, your doctor could use an Electromyogram to evaluate the electrical activity of your muscles. This test helps to determine if muscle damage has occurred, and is also used to rule out other conditions. Fortunately, when carpal tunnel syndrome is treated properly, most people find that proper wrist and hand function is easily restored.
