I am 26 years old. I think I have hyperthyroidism as I have done an extensive research on it and I have all the symptoms of hyperthyroidism namely - ?tremors which I never had before, especially in head, occasionally in hands as well (*)?restlessness ?agitation ?anxiety ?muscle weakness ?sensitivity to light (specially sunlight)?extreme weight loss inspite of increased appetite (*)?rapid heart rate (*)?intolerance to heat ?nervousness ?irritability ?soft velvety body skin (*)?increased appetite (*)?heart palpitation (*)?fatigue, weakness ?decreased concentration (*)?fine / brittled hair (*)?sleep disturbances (*)?regular sore throat (*)?most time difficulty in swallowing problem comes with sore throat (*)?trouble breathing even while resting (*)but I have been given levothyroxine - 75 mcg' medicine which is for hypothyroidism. I do not have even a single symptom of hypothyroidism. I am very confused and I strongly think that I have been diagnosed completely incorrectly. My mother has hypothyroidism and I can see all hypothyroid symptoms in her easily. I have went to 2 doctors till now (never went to an endocrinologist though) and I want to know how to get extensively diagnosed properly. So that, I know if I have any autoimmune disease, or simply hyperthyroidism. Can anyone of you please help me out. I am looking for a doctor who could diagnose me in an extensive manner.
