I keep having spells of extreme irritability, waves of nausea, feeling very hot or very cold, feeling spaced out, food cravings, weakness, feeling shaky, trouble concentrating and speaking (can t concentrate to speak normally). The last episode has been over the past 3 days. I have a history of a thyroid goiter, that has been increasing again recently, normal thyroid labs. I am usually physically active and i am otherwise healthy. My labs always come out normal...I m very frustrated with the whole situation.
