2. Hand and Forearm Pain
Tingling and numbness in the thumb and fingers can become painful. This symptom usually worsens at night and can feel like an electric shock, interrupting sleep in severe cases. Over time, pain can also move from the thumb and fingers into the hand and forearm. Sharp, shooting pain throughout the hand and forearm is a common symptom of chronic carpal tunnel syndrome. If this symptom begins to affect your sleep or capabilities at work, it is important to consult your doctor for pain relief methods.
