Hi Doctor I am middle 50 and had my sever heart palpitation last Monday with 130 and went to the hospital by ambulance, I was immediately treated as heart attack. But discharged 6 hours later as they can t found any heart attack evidence. My doctor taken my blood exam and just found now my TSH is less than 0.005, and he told me that I am more likely have thyroid problem. Please advise me what treatment I need from now? If it confirms (more likely will), means I need take medicine rest of life? will the medicine that current treat for all thyroid penitent has potential damage your lever or other part of your body? I am very worried and if yes, will the surge be the better option?
