My daughter has been having spells of dissyness, slurred speech, she can hear people talk to her but can't respond, her hand moves without her moving it and it feels numb. . They say she has an enlarged thyroid but all the blood tests come out fine. . They did a full blood work up and she is fine with those numbers. . Today she went into the emergency room and they put a heart monitor for 48 hours and sent her home. . Could the thyroid have anything to do with this, is there anything else she should do, and should she try exceeding or should she take it easy
