Endocrinologist,  's  Response
Hello there,

Synthroid is the trade name for levothyroxine. It is used for replacing thyroid hormones in the body, in hypothyroid patients.

With the symptoms that you have told, apparently, it seems that you must be hypothyroid, thats why you were put on synthyroid initially and thats why you feel better while taking synthyroid.

But history has to be supplemented with clinical exam and investigations. Without knowing about your initial thyroid profile and other relevant investigations, it would not be wise to draw any conclusion regarding whether you actually need thyroid hormone supplementation or not.

So I suggest you to see an Endocrinologist and have him review you clinical history and previous investigations, for appropriate solution to the problem.

Hope it helps..........
