Good day! The most common answer to the symptoms you are experiencing is Carpal Tunnel. It is compression of a main nerve in your hand that comes from repeated movement and compression of the wrist. The symptoms can occur often at night due to accumulated tension throughout the day. As for the palpation s, how high is your heart-rate? Common causes can be coffee, dehydration and or stress. If you experience any other symptoms certainly see a physician for a Cardiac Check-up. As for the wrist, try taking breaks from repetitive tasks involving your hands. There are wrist splints that can be bought over the counter, they are very useful. Stretching exercises may also help: make a fist and then spread your fingers out. I hope this advise can be helpful, and leads you in the correct direction. You have my warm regards.
