Hi doctor,
I have a eleven year old son. He always feels dizzy, fatigued, and palpitate recently especially after exercise and eating food. He also feels numb in the throat. Yesterday, after a nap, he woke up with dizzy and numb all over and hard to talk. We called 911, did the ECG test, blood sugar and other blood test , it shows normal. We also did the thyroid test, it also shows normal. He has severe allergy and he grows so fast this month, almost 3cm in this month. could it be "Hormonal Imbalance"?
