Symptoms:

• Numbness or tingling in the thumb and next two or three fingers of one or both hands
• Numbness or tingling of the palm of the hand
• Pain extending to the elbow

• Problems with fine finger movements (coordination) in one or both hands
• Wasting away of the muscle under the thumb (in advanced or long-term cases)

Signs and tests:

During a physical examination, the doctor may find:

• Numbness in the palm, thumb, index finger, middle finger, and thumb side of the ring finger
• Weak hand grip
• Tapping over the median nerve at the wrist may cause pain to shoot from the wrist to the hand (this is called Tinel's sign)
• Bending the wrist forward all the way for 60 seconds will usually result in numbness, tingling, or weakness (this is called Phalen's test)

Tests may include:

• Electromyography
• Nerve conduction velocity
• Wrist x-rays should be done to rule out other problems (such as wrist arthritis)
