Hi. New to this forum and wondering if someone can answer a question for me please. Had a hemithyroidectomy in Feb this yr for poss cancer (it wasnt) but had a few symptoms since-nothing major yet-just some back, hip and stomach aches. Just wondering about asking to be put on low dose of thyroxine, eg 25mg, but worrying that if its not really needed that it may cause the remaining gland to stop working properly and 'atrophy'. My Tsh has risen from 0.66 to 1.66 but Ft4 seems to be around the same at 16. Think Ft3 around mid range. Have been devastated by this unnecessary op (no probs with thyroid function prev) and wondering if low dose of thyroxine would be helpful to prevent ill health escalating but dont want to suppress function of remaining gland. Would appreciate any insight. Thanks.
