    stop synthroid
    I don't feel like the synthroid is making a difference even though the dose has been increased. Will it be ok if I stop taking the synthroid? What will happen if I stop taking the synthroid?

    I hope you did not stop-talk to your doctor. Thyroid hormone replacement takes a very long time to regulate. Good luck!

    Cytomel is the most recent medication. Have had the issues for a long time before that. And went off the Synthroid for 5 months to test that theory. But thank you so much for your input.

    Please see if your doctor can do a biopsy on the lump. That should be your next step. I am 23 and Ihave thyroid cancer and I think it's silly when doctors want to "watch" your lump. It makes no sense to me. I hope everything goes well!!
