DH has been taking Levothyroxine 25 mg for "slightly" elevated thyroid since late July / early August. Last week he went for a follow up visit to see how he was doing. Doctor's office just called and told him that apparently its still elevated, or more elevated. I don't know and DH doesn't remember what it was the last time, but this time its 5.7. He has to go in to talk to the doctor and have more blood tests Friday. Does anybody know what it might mean that the medicine didn't help? Do I need to be worried (I am anyway).
