Hello there.
I can understand your concern.
Why have you not attached the reports of the same?
What is 6.66? Is it t3,t4 or
tsh?
You see, its always better to attach the reports with a question that you post.
Nothing to be scared of
thyroid.
Many people in this world are having thyroid imbalances but leading a perfectly normal life.
You just have to take one tablet everyday thats it and do not miss it.
Do not fall to quacks who claim cure of thyroid issues by taking their medicines.
You will be alright.
Best regards.
Dr. Anil kumar jain.
