Andrea, so sorry about this development. Have you been tested for anything else? One thing you could do for yourself is avoid soy and things in the cabbage family, limit carbs and increase exercise. I guess that's 3 things. Those all have a direct bearing on thyroid.
I'm in a strange situation. All of a sudden, my TSH has jumped to 22, even though I do all the above, keep my weight down, and take my levoxyl every day on an empty stomach and wait an hour before eating. Anyone else ever had this happen? The doctor seems to think it might have been a bad batch of levoxyl or lab results were mixed up. Anyway, he upped the dosage and I have to go back in 3 weeks to be retested...just when I thought things were getting better.
