If you are experiencing the symptoms of CTS, such as tingling, numbness, or itching in the palm and the fingers or pain in the wrist that feels like an electric shock and radiates up the arm to the shoulder or down into the palm and/or fingers, you should see your doctor to get checked out. Early diagnosis and treatment are important to avoid permanent damage to the median nerve. If the symptoms have progressed to the point where your palm muscles have atrophied or you have lost grip strength, you should see the doctor right away.
