Thank you for your response. It's very helpful to me. Yes, I do have symptoms, but they seem to be mixed, some hypo- & some hyper- thryoid characteristics, i.e. weight gain, anxiety, fatigue, frequent bowel movements, inability to focus/concentrate, can't remember squat, anxiety, intolerance to heat, itchy skin, brachycardia, shortness of breath, hoarseness, difficulty swallowing, palpitations, muscle stiffness and joint pain.
