I am a thyroid patient for last 15 years. The blood test report of last January,2012, it was slightly high for TSH , but T3,T4 was normal. Now, I have made a test again yesterday, and the report came that TSH become too low that means it is now below normal i.e. 0.37. I am taking the medicine thyronorm 125 per day, now the question is what to do now?
