If you are in a low iodine area maybe it will help, but I think you can get your TSH nice
and low as the Dr said below 1
and there is a likelyhood the goitre will shrink on Armour thyroid or if you really have to levothyroxine (not so good in my humble opinion and in my experence but we are all different),
Unless you have cancer I think you would be unwise to have your gland removed by the way even if it is offered, its really not needed.
Hope you get good treatment.
