Tremble: Your 5th digit is least controlled from a muscle and tendon stand point. Possible you have done this for awhile and not noticed. However, if you feel that it is significant get checked. I would consider electrolye, calcium, magnesium imbalance possible. Also, thyroid should probably be checked. Other symptoms like fatigue, heat intollernance, skin changes?
